Question

When 4L of nitrogen completely reacts with hydrogen, what would be the volume of ammonia gas formed?

Answer 1

the volume of ammonia=4/22.4*
22.4liters=4liters

Answer 2

According to the equation, for 1 molecule of nitrogen (N2) gas and 3 molecules of hydrogen (H2) gas, 2 molecules of ammonia gas (NH3) are produced. So the mole ratio of Nitrogen to Ammonia is 1:2.

Assuming both Nitrogen gas and Ammonia gas are close approximations to an ideal gas, a mole of each occupies the same volume. So the volume ratio is the same as the mole ratio.

(Vammonia) / 4.74L = 2 / 1
