The Italian scientist Amedeo Avogadro studied the amount of matter in gases. He calculated that under normal conditions, the same volume of any gas contains the same amount of substance.
The main measure of the amount of a substance is the mole. One mole of any gas (in accordance with Avogadro’s law) at n.u. contains 22.4 liters of gas. This constant is called the molar volume of the gas Vm.
Therefore, in order to determine the amount of ammonia substance, it is necessary to divide the gas volume by the molar volume.
N = V / Vm = 44.8 / 22.4 = 2 mol
Answer: the amount of ammonia substance is 2 mol
