Question

A sample of sulfur has a mass of 232 grams. How many moles of sulfur are in the sample? 7.24 mol of S 7.235 mol of S 8.00 mol of S

Answer 1

Sulfur has atomic mass of 32.06 so you divide 232 by 32.06 to get 7.24 mol using sig figs
answer= 7.24 mol of S

Answer 2

7.235 mol of S are in the given sample

Step-by-step explanation:

Number of mol calculated as follows:

Number of mol = amount in g / molar mass

Given that amount of sulfur = 232 grams.

Molar mass of sulfur = 32.065 g/ mol

Therefore the number of S is calculated as follows:

Number of mol = 232 grams/ 32.065 g/ mol

= 7.235 mol

7.235 mol of S are in the given sample
