Final answer:
The percent composition of Carbon in the substance is 30.25%.
Step-by-step explanation:
To find the percent composition of Carbon in the substance, we need to calculate the mass percent of Carbon in the total mass of the substance. The total mass of the substance is the sum of the masses of Carbon, Sulfur, and Oxygen.
1. Calculate the total mass of the substance:
Total mass = mass of Carbon + mass of Sulfur + mass of Oxygen
Total mass = 19.19 g + 29.26 g + 15.08 g = 63.53 g
2. Calculate the mass percent of Carbon:
Mass percent of Carbon = (mass of Carbon / total mass) × 100
Mass percent of Carbon = (19.19 g / 63.53 g) × 100 = 30.25%
