nitrogen gas was produced in a reaction and collected over water. A 45.2 mL sample of gas was collected over water at 25oC. The reading on the barometer in the laboratory was 0.97 atm. The vapor pressure of water is 23.76 mmHg at 25oC. Find the mass of nitrogen gas collected.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
