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

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. Identify the empirical formula and the molar mass of the compound: Empirical formula = C₂H₄, Molar mass of the compound = 112 g/mol.
2. Calculate the molar mass of the empirical formula: Molar mass of C₂H₄ = (2 × 12.01 g/mol) + (4 × 1.008 g/mol) = 24.02 g/mol + 4.032 g/mol = 28.052 g/mol.
3. Determine the value of ...
