Ammonia is often formed by reacting nitrogen and hydrogen gases. How many liters of ammonia gas can be formed from 23.7 L of hydrogen gas at 93.0°C and a pressure of 38.9 kPa?

Answer 1

N2 + 3H2 ==> 2NH3

If you want the volume of NH3 at the same conditions, it is just 23.7 L x (2 mols NH3/3 mols H2) = ?

If you want it at STP, use PV = nRT and convert.
