Chapter 10, Problem 33E

Calcium cyanamide is a common fertilizer. When mixed with water in the soil, it reacts to produce calcium carbonate and ammonia: ${\text{CaCN}}_{\text{2}}+3{\text{H}}_{\text{2}}\text{O}\to {\text{CaCO}}_{\text{3}}+2{\text{NH}}_{\text{3}}$. How much ammonia can be obtained from $7.25\text{g}$ of calcium cyanamide in a laboratory experiment in which the percentage yield will be $92.8\%$?
