Question Analysis
This question evaluates the student's ability to determine the molecular formula from the given empirical formula and molar mass.

Key Concept Explanation
The molecular formula is a multiple of the empirical formula, and this multiple (n) can be found by dividing the molar mass of the compound by the molar mass of the empirical formula.

Step-by-step Solution
1. Calculate the molar mass of the empirical formula C₂H₄O: (2 × 12.01) + (4 × 1.008) + 16.00 = 44.052 g/mol.
2. Determine the value of n by dividing the molar mass of the compound by the molar mass of the empirical formula: 132 g/mol ÷ 44.052 g/mol ≈ 3.
3. Multiply each subscript...
