Determine what volume is 0.2 mol NH3?

Given:
n (NH3) = 0.2 mol
Vm = 22.4 l / mol

To find:
V (NH3) -?

Decision:
1) Initial formula (under normal conditions):
n (NH3) = V (NH3) / Vm;
2) Calculate the volume of NH3 (under normal conditions):
V (NH3) = n (NH3) * Vm = 0.2 * 22.4 = 4.48 liters.

Answer: The volume of NH3 (under normal conditions) is 4.48 liters.
