Question

A sample of sulfur has a mass of 232 grams. How many moles of sulfur are in the sample?

Answer 1

Sulfur has a molar mass of 32.1 g/mole. So 232 g S / 32.1 g S = 7.22 moles 

Answer 2

Answer : The number of moles of sulfur present in sample are, 7.343 moles

Solution : Given,

Mass of sulfur = 232 gram

Molar mass of sulfur = 32 g/mole

Formula used :

`\text{Moles}=\frac{\text{Given mass}}{\text{Molar mass}}`

`\text{Moles of Sulfur}=\frac{\text{Mass of Sulfur}}{\text{Molar mass of Sulfur}}=(232g)/(32g/mole)=7.343moles`

Therefore, the number of moles of sulfur present in sample are, 7.343 moles
