The molar mass of the gas, given that 3.25 g of the gas occupied 2.56 L is 30.66g/mol

To obtain the molar mass of the gas, we shall first obtain the number of mole of the gas. This can be obtained as follow:

PV = nRT

0.95 × 2.56 = n × 0.0821 × 280

Divide both sides by (0.0821 × 280)

n = (0.95 × 2.56) / (0.0821 × 280)

n = 0.106 mole

Haven obtain the mole of the gas, we shall determine the molar mass of the gas as follow:

Molar mass = mass / mole

Molar mass of gas = 3.25 / 0.106

Molar mass of gas = 30.66g/mol

Thus, the molar mass of the gas is 30.66g/mol

Explanation:

7.77 × 10^(-4) in standard notation is 0.000777.

To convert a number from scientific notation to standard notation, we need to multiply the coefficient (7.77) by the power of 10 (-4). In this case, the given number is 7.77 × 10^(-4).

To convert it to standard notation, we need to move the decimal point to the left or right based on the exponent of 10. Since the exponent is negative (-4), we move the decimal point four places to the left.

Starting with the number 7.77, we move the decimal point four places to the left:

7.77 → 0.000777

Therefore, 7.77 × 10^(-4) in standard notation is 0.000777.

In standard notation, we express the number without any exponent or power of 10. It is a way to represent the number in a more conventional format, where the decimal point is placed in relation to the significant digits of the number.

Remember to correctly place the decimal point when converting between scientific notation and standard notation, considering the positive or negative exponent of 10.

Explanation:

Electron is a subatomic particle with a negative charge of -1e unlike the proton which has a positive charge of +1e

In an atom, an electron has a net negative charge revolving in orbits around the nucleus.

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

To solve this problem, we can use the combined gas law, which states:

(P1 * V1) / T1 = (P2 * V2) / T2

Where:

P1 = Initial pressure (720 mm Hg)

V1 = Initial volume (1.00 L)

T1 = Initial temperature (20.0°C + 273.15) in Kelvin

P2 = Final pressure (360 mm Hg)

V2 = Final volume (2.14 L)

T2 = Final temperature (to be determined) in Kelvin

First, let's convert the initial temperature from Celsius to Kelvin:

T1 = 20.0°C + 273.15 = 293.15 K

Now, we can substitute the given values into the combined gas law equation and solve for T2:

(720 mm Hg * 1.00 L) / 293.15 K = (360 mm Hg * 2.14 L) / T2

Cross-multiplying and solving for T2:

720 mm Hg * 1.00 L * T2 = 360 mm Hg * 2.14 L * 293.15 K

720 T2 = 360 * 2.14 * 293.15

720 T2 = 226,607.88

T2 = 226,607.88 / 720

T2 ≈ 314.45 K

NO2(OH) dissolved in water is an example of an acidic salt.

Acidic salts are formed when a strong acid and a weak base react together. They are acidic in solution because they dissociate to form H+ ions and an anion. In this case, the acidic salt is NO2(OH), which when dissolved in water, dissociates to form H+ ions and OH- ions, resulting in an acidic solution.

Ni(OH)2 dissolved only in an acidic solution is an example of a basic salt.

Basic salts are formed when a strong base and a weak acid react together. They are basic in solution because they dissociate to form hydroxide ions (OH-). In this case, the basic salt is Ni(OH)2, which when dissolved only in an acidic solution will dissociate to form Ni2+ ions and OH- ions resulting in a basic solution.

The total number of moles NH3 is 1.00 mole, under the condition that the reaction is of 14. 0 g N2.

The given balanced chemical equation for the reaction of nitrogen gas (N2) and hydrogen gas (H2) to form ammonia gas (NH₃) is
N₂(g) + 3H₂(g) → 2NH₃(g)

The molar mass of N₂ is 28.01 g/mol. To evaluate the number of moles of N₂ in 14.0 g of N₂ we divide the mass by the molar mass
Number of moles of N₂ = Mass of N₂ / Molar mass of N₂
Number of moles of N₂ = 14.0 g / 28.01 g/mol
Number of moles of N₂ = 0.4998 mol

Then, the number of moles of NH3 that would form from the complete reaction of 14.0 g N2 can be evaluated
Number of moles of NH₃ = Number of moles of N₂ × (2 moles NH₃ / 1 mole N₂)
Number of moles of NH₃ = 0.4998 mol × (2 mol NH₃ / 1 mol N₂)
Number of moles of NH₃ = 0.9996 mol

Hence, approximately 1.00 mole of NH₃ would form from the complete reaction of 14.0 g N₂.

The concentration of koh is 0.15 M.

To determine the concentration of KOH (potassium hydroxide) in the solution, we can use the concept of stoichiometry and the balanced chemical equation for the neutralization reaction between HCl (hydrochloric acid) and KOH.

The balanced equation for the reaction is:

HCl + KOH → KCl + H₂O

From the equation, we can see that the molar ratio between HCl and KOH is 1:1. This means that one mole of HCl reacts with one mole of KOH.

First, let's calculate the number of moles of HCl in the 30 ml of 0.25 M (mol/L) HCl solution:

moles of HCl = volume (L) × concentration (M)

moles of HCl = 0.030 L × 0.25 M

moles of HCl = 0.0075 mol

Since the stoichiometry of the reaction is 1:1, the number of moles of KOH in the 50 ml sample is also 0.0075 mol.

Now, let's calculate the concentration of KOH in the 50 ml solution:

concentration (M) = moles of KOH / volume (L)

concentration (M) = 0.0075 mol / 0.050 L

concentration (M) = 0.15 M

Therefore, the concentration of KOH in the solution is 0.15 M.

In conclusion, by utilizing the stoichiometry of the neutralization reaction and calculating the number of moles of HCl used, we can determine the number of moles of KOH in the solution. Dividing this by the volume of the KOH solution gives us the concentration of KOH, which is 0.15 M in this case.

Answer:

Ca3(PO4)2 = P2O5 + CaO - Chemical Equation Balancer.

Explanation:

Answer:

Ca3(PO4)2

Explanation:

Answer:

0.202M

Explanation:

you will want to use C₁V₁=C₂V₂ to solve for this.

C₁ is the initial concentration, in this problem it is .458 mol/L or M

V₁ is the initial volume, so it will be the 22.0 mL or 0.0220L

C₂ is the new concentration but here it is unknown.

V₂ is the new volume which is 50.0 mL or 0.0500L.

1. So now we plug this information in to the equation:

\((.458 mol/l)(0.0220L)=(C_{2} )(0.0500L)\)

2. We then do algebra to get C₂ alone:

\(C_{2} =\frac{(.458 mol/L)(0.0220L)}{(0.0500L)} =0.20152 mol/L or M\)

The liters cancel out and take note of the significant figures, there are 3 digits in all numbers in the question, so that means your answer must contain 3 sig figs. The answer 0.0202 rounded.

** instead of converting the mL to L you can also just keep them mL since they will be crossed out anyway. You will still get the correct answer.
