Step 1

Given:

Mass percent of sulfur = 40.05 %.

Mass percent of oxygen = 59.95 %.

Molar mass of oxygen = 16 g/mol.

Molar mass of sulfur = 32 g/mol.

Conversion of mass percent to gram:

Since we are having mass percent, it is convenient to use 100 g of the compound as the starting material. Thus, in the 100 g of sample of above compound 40.05 g sulfur and 59.95 g of oxygen.

Step 2

Calculation for number of sulfur:

Step 3

Calculation for numb...
