1. Getting ammonia occurs according to the reaction equation:
3H2 + N2 = 2NH3;
2.Calculate the chemical amount of ammonia:
n (NH3) = m (NH3): M (NH3);
M (NH3) = 14 + 3 = 17 g / mol;
n (NH3) = 34: 17 = 2 mol;
3.from the proportion according to the equation, we find the amount of hydrogen:
n (H2) = 3 * n (NH3): 2 = 3 * 2: 2 = 3 mol.
