The interaction of hydrogen and nitrogen formed 300 g of ammonia. What is the mass of hydrogen

The interaction of hydrogen and nitrogen formed 300 g of ammonia. What is the mass of hydrogen that has entered into reaction?

1. The formation of ammonia occurs according to the reaction equation:

3H2 + N2 = 2NH3;

2. find the chemical amount of ammonia:

n (NH3) = m (NH3): M (NH3);

M (NH3) = 14 + 3 = 17 g / mol;

n (NH3) = 300: 17 = 17.647 mol;

3.determine the amount of hydrogen:

n (H2) = n (NH3) * 3: 2 = 17.647 * 3: 2 = 26.47 mol;

4.Calculate the mass of hydrogen that has reacted:

m (H2) = n (H2) * M (H2) = 26.47 * 2 = 52.94 g.

Answer: 52.94 g.
