A chemist used $2.00\,\text{dm}^3$ of nitrogen gas, measured at room conditions, and allowed it to react with an excess volume of hydrogen gas to make ammonia. Only $15.0\%$ of the nitrogen gas went on to react to form ammonia. What mass of ammonia was produced?
- A$0.213\,\text{g}$
- B$0.425\,\text{g}$
- C$1.42\,\text{g}$
- D$2.83\,\text{g}$
