The formula for mustard gas used in chemical warfare is C4H₈SCl₂ (159.09 g/mol).What is the percentage of hydrogen in the compound?

Question

Quizplus · Accepted Answer

The percentage of hydrogen in the compound can be calculated by finding the mass of hydrogen in the formula and dividing it by the molar mass of the entire compound, then multiplying by 100. The formula C4H8SCl2 has 8 hydrogen atoms, with each hydrogen atom having an approximate mass of 1.01 g/mol. Therefore, the mass of hydrogen in the compound is 8 * 1.01 = 8.08 g/mol. The molar mass of the compound is given as 159.09 g/mol. The percentage of hydrogen is (8.08 / 159.09) * 100 = 5.08%.
