Question Analysis
This question tests the student's ability to calculate the percent composition of an element in a simple binary compound.

Key Concept Explanation
Percent composition is determined by dividing the total mass of the element in one mole of the compound by the molar mass of the compound, then multiplying by 100%.

Step-by-step Solution
1. Calculate the molar mass of : Molar mass = (2 × 1.0) + 32.1 = 2.0 + 32.1 = 34.1 g/mol.
2. Calculate the total mass of sulfur in one mole of
