What is the empirical formula for a compound that is made of 7.00 g of carbon and 1.75 grams of hydrogen?

Question

Quizplus · Accepted Answer

To find the empirical formula, first, the amount of moles of each element is calculated: for carbon (C), 7.00 g divided by its molar mass (approximately 12.01 g/mol) gives about 0.583 moles; for hydrogen (H), 1.75 g divided by its molar mass (approximately 1.008 g/mol) gives about 1.736 moles. The ratio of H to C is approximately 3:1, making the empirical formula CH₃.
