Volume 3 mol of ammonia NH3 under normal conditions.

The volume is calculated by the formula: V = n × Vm, where Vm is the molar volume, under normal conditions (n.o.) for substances it is constant and equal to 22.4 l / mol.
n (NH3) = 3 mol
Vm = 22.4 l / mol
V (NH3) = 3 mol × 22.4 g / mol = 67.2 L
Answer: 67.2
