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 relationship between the empirical formula and the molecular formula is given by the equation: molecular molar mass = n × (empirical formula molar mass), where n is a positive integer.

Step-by-step Solution
1. Calculate the molar mass of the empirical formula C₂H₃O: (2 × 12.01) + (3 × 1.008) + 16.00 = 43.044 g/mol.
2. Determine the value of n: n = molecular molar mass / empirical formula molar mass = 162 g/mol / 43.044 g/mol ≈ 3.76.
