# How Many Moles of NH3 Can Be Produced from 13.5 mol of H2 and Excess N2?

## 3 H2 (g) + N2 (g)→ 2 NH3(g)a

In this article you can find the answer for How Many Moles of NH3 Can Be Produced from 13.5 mol of H2 and Excess N2. Also you can find answers for:

• How many grams of NH3 can be produced from 4.90 mol of N2 and excess H2
• How many grams of H2 are needed to produce 12.74 g of NH3?
• How many molecules (not moles) of NH3 are produced from 1.05×10^-4 g of H2?

How Many Moles of NH3 Can Be Produced from 13.5 mol of H2 and Excess N2?

For every 3 moles of H2, 2 of NH3 can be produced. If we multiply the amount of hydrogen by 2/3 and we can get the answer.

9 moles of NH3 are produced from 13.5 mol of H2 and excess N2.

## How many grams of NH3 can be produced from 4.90 mol ofN2 and excess H2?

N2 + 3H2 = 2NH3

1 mol of nitrogen + hydrogen produces 2(14+3) = 34 grams NH3

4.9 mol of N and H produces 34 * 4.9 grams NH3

Answer is 166.6 grams of NH3 can be produced from 4.90 mol of N2 and excess H2.

## How many grams of H2 are needed to produce 12.74 g of NH3?

M (NH3) = 14.01 + 1.008*3 = 17.034

m (NH3 = 12.74

n(NH3 = 12.74/17.034 = 0.749

For every two moles of NH3, you need 3 moles of H2.

0.749 * 3/2 moles of H2 = 1.12 mol

M(H2 = 2.016
m = n*M = 1.12 mol * 2.016 g/mol = 2.25

About 2.25 grams of H2

Answer is 2.25 grams of H2 are needed to produce 12.74 g of NH3.

## How many molecules (not moles) of NH3 are produced from 1.05×10^-4 g of H2?

m(NH₃) = 1.05 × 10⁻⁴ g NH₃

M(NH₃) = 14.007 g/mol N + (3 × 1.008 g/mol H) = 17.031 g NH₃/mol NH₃

n(NH₃) = 1.05 × 10⁻⁴ g NH₃/17.031 g NH₃/mol NH₃ = 6.16 × 10^-6 mol NH₃

Calculate the number of molecules of NH₃ in 6.16 × 10^-6 mol.

1 mole of molecules = 6.022 × 10²³ molecules

6.16 × 10^-6 mol NH₃ × 6.022 × 10²³ NH₃ molecules/mol NH₃ = 37.09 × 10^17 NH₃

The number of molecules of NH3 are produced from 1.05 × 10^-4 g is 37.09 × 10^17.
