What is the mass of a sample of sulfur with a volume of 5.0 cm3

0.00714 g

Explanation:

We know that the volume of one mole of a substance is 22400 cm^3

Thus;

1 mole of sulphur occupies 22400 cm^3

x moles of sulphur occupies 5.0 cm3

x = 5.0 cm3 * 1 mole/22400 cm^3

x = 2.23 * 10^-4 moles

Molar mass of sulphur = 32 g/mol

Mass of sulphur = 2.23 * 10^-4 moles * 32 g/mol

Mass of sulphur = 0.00714 g
