Question Analysis
This question assesses 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 CH₂O: 12.01 + (2 × 1.008) + 16.00 ≈ 30.03 g/mol.
2. Determine the value of n by dividing the molar mass of the compound by the molar mass of the empirical formula: 150 g/mol ÷ 30.03 g/mol ≈ 4.99.
3. Round n to the nearest whole numb...
