mols
Enter

Answer 1

To determine the number of moles of Sulfur (S) in the sample, divide the mass of Sulfur by its molar mass.

Step-by-step explanation:

To determine the number of moles of Sulfur (S) in the sample, we need to convert the mass of Sulfur to moles using its molar mass. The molar mass of Sulfur (S) is approximately 32 g/mol.

Given that the sample contains 42.1 g of Sulfur, we can use the following calculation:

Moles of Sulfur = Mass of Sulfur / Molar Mass of Sulfur

Moles of Sulfur = 42.1 g / 32 g/mol = 1.315625 mol
