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

Step-by-step Solution
1. Calculate the molar mass of the empirical formula CH₂O: .
2. Determine the value of n by dividing the molar mass of the compound by the molar mass of the empirical formula:
