Question

The elemental composition of a compound is 54.2% C, 9.2% H, and 36.6% O. If the molar mass of the compound is 132 g/mol, the molecular formula of the compound is:

• A. \( \text{C}_6 \text{H}_{12} \text{O}_6 \)
• B. \( \text{C}_6 \text{H}_{12} \text{O}_3 \)
• C. \( \text{C}_4 \text{H}_9 \text{O}_3 \)
• D. \( \text{C}_4 \text{H}_8 \text{O}_2 \)

Hint:

The empirical formula can help determine the molecular formula by using the molar mass.

Answer 1

The Correct Option is A

- Establish the empirical formula by calculating the mole ratio of C, H, and O. - Subsequently, multiply by the molar mass to derive the molecular formula. Final Answer: Option (1).
