Calculate the volume of ammonia if 5.6 liters of nitrogen reacts with hydrogen.

N2 + 3H2 = 2NH3

In the case of solid or liquid substances, the mass must be converted to the amount of the substance. Since the molar volume Vm of different gases is the same under the same conditions (in our case, n.c. – 0 ° C, 1 atmosphere), it makes no sense to go from volume to the amount of matter.

According to the reaction equation, 3 liters of hydrogen reacts with 1 liter of nitrogen, and 2 liters of ammonia are formed.

This means that 5.6 * 3 = 16.8 liters of hydrogen will interact with 5.6 liters of nitrogen, while 5.6 * 2 = 11.2 liters of ammonia will be formed.
