How much does 48 grams of oxygen take?

To solve the problem, we write down given: m (O2) = 48 g
Find: V (O2) -?
Let’s write down the formula for calculating the volume.
V = v * Vm, where
V – volume
v – amount of substance (mol)
Vm – constant molar volume, which is 22.4 l / mol
Let’s calculate the amount of substance according to the formula:
v = m / M, where
m – mass of matter
M – molar mass
M (O2) = 16 * 2 = 32 g / mol
We substitute our data into the formula for calculating the amount of substance, we get:
v = 48 g / 32 g / mol = 1.5 mol
Let’s calculate the volume of oxygen
V (O2) = 1.5 mol * 22.4 L / mol = 33.6 L
Answer: V (O2) = 33.6 l
