Question Analysis
This question evaluates the student's ability to determine the molecular formula from the empirical formula and the 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. Determine the molar mass of the empirical formula C₂H₄O: (2 × 12.01) + (4 × 1.008) + 16.00 = 44.052 g/mol.
2. Calculate n: n = 176 g/mol / 44.052 g/mol ≈ 4.
3. Multiply the subscripts in the empirical formula by n: C₂×₄H₄×₄O×₄ =
