Chapter 10, Problem 35E

The Haber process for making ammonia from nitrogen in the air is given by the equation ${\text{N}}_{\text{2}}+3{\text{H}}_{\text{2}}\to 2{\text{NH}}_{\text{3}}$. Calculate the mass of hydrogen that must be supplied to make $5.00\times {10}^2\text{kg}$ of ammonia in a system that has an $88.8\%$ yield.
