Calculate the mass of 5.6 L of oxygen measured under normal conditions.

In order to calculate the mass of oxygen under normal conditions, we use the following formulas:
First, we find out the amount of substance, for this we divide the volume by the molar volume, and the following values are obtained:
5.6 ÷ 22.4 = 0.25 mol
Further, through the amount of substance, we find the mass, according to the following formula, we get the following values:
32 x 0.25 = 8 g
M (O2) = 32 g / mol
Therefore, the mass of 5.6 liters of oxygen is 80
Answer: 8 g.
