Question 69

The equation for the synthesis of ammonia in the industrial Haber process is:

\text{N}_2 + 3\text{H}_2 \rightarrow 2\text{NH}_3

Calculate the maximum mass of ammonia ( $NH3\text{NH}_3$ ) that could be produced if 126 g of nitrogen gas ( $N2\text{N}_2$ ) reacts completely with excess hydrogen gas.

(relative formula masses: $N2=28\text{N}_2 = 28$ ; $NH3=17\text{NH}_3 = 17$ )
