Question
**Question 86:** A compound contains only C, H, and N. Combustion of 35.0 mg of the compound produces 33.5 mg CO₂ and 41.1 mg H₂O. What is the empirical formula of the compound? **Question 87:** Cumene is a compound containing only carbon and hydrogen that is used in the production of acetone and phenol in the chemical industry. Combustion of 47.6 mg cumene produces some CO₂ and 42.8 mg water. The molar mass of cumene is between 115 and 125 g/mol. Determine the empirical and molecular formulas. **Question 88:** A compound contains only carbon, hydrogen, and oxygen. Combustion of 106.8 mg of the compound yields 160.1 mg CO₂ and 43.7 mg H₂O. The molar mass of the compound is 176.1 g/mol. What are the empirical and molecular formulas of the compound?
