A sample of sulfur has a mass of 232 grams. How many moles of sulfur are in the sample?
Sulfur has a molar mass of 32.1 g/mole. So 232 g S / 32.1 g S = 7.22 moles
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 :
\(\text{Moles}=\frac{\text{Given mass}}{\text{Molar mass}}\)
\(\text{Moles of Sulfur}=\frac{\text{Mass of Sulfur}}{\text{Molar mass of Sulfur}}=\frac{232g}{32g/mole}=7.343moles\)
Therefore, the number of moles of sulfur present in sample are, 7.343 moles
