Final answer:
To determine the percent composition of a compound, divide the mass of each element by the total mass of the compound and multiply by 100. The question, however, lacks sufficient details to solve for the specific compound in question, which only contains sulfur and nitrogen.
Step-by-step explanation:
The question asks for the percent composition of a compound that contains only sulfur and nitrogen. Although the initial part of the question seems to have an error stating '69.6% what', it likely aims to inquire about which of the two elements, sulfur or nitrogen, constitutes 69.6% of the compound. However, additional details are not provided to answer this specifically. To determine the percent composition of any compound, you would divide the mass of each element by the total mass of the compound and then multiply by 100 to get a percentage.
For example, the analysis of a 12.04-g sample of a liquid compound that consisted of 7.34 g carbon, 1.85 g hydrogen, and 2.85 g nitrogen shows that its percent composition is 61.0% carbon, 15.4% hydrogen, and 23.7% nitrogen.
Similarly, the exercise relating to sulfuric acid demonstrates calculating percent composition. In the case of the 196.0 g of sulfuric acid containing 64.0 g oxygen and 4.0 g hydrogen:
- Oxygen percent composition: (64.0 g / 196.0 g) * 100 = 32.65%
- Hydrogen percent composition: (4.0 g / 196.0 g) * 100 = 2.04%
The sulfur composition would be determined by subtracting the percent compositions of oxygen and hydrogen from 100%.
