Under normal conditions, any gas occupies a volume of 22.4 liters. Let’s convert the mass of oxygen into the amount of substance, and then calculate the volume.
The molar mass of oxygen is 32 g / mol
n = m / M = 22.4 / 32 = 0.7 mol
Now, knowing the amount of substance, we calculate the volume of the gas:
V = 0.7 * 22.4 = 15.68 l.
Answer: 15.68 liters.
