NEET Chemistry Atomic & Molecular Mass MCQ Question
A compound is composed of 40% carbon, 6.7% hydrogen, and 53.3% oxygen by mass. Calculate the empirical formula of the compound.
CH2O
C2H4O2
CH3O
C2H6O
Correct Answer
Detailed Explanation
The empirical formula is determined by converting the percentage composition to moles. Carbon: 40%/12 = 3.33 mol, Hydrogen: 6.7%/1 = 6.7 mol, Oxygen: 53.3%/16 = 3.33 mol. Simplifying the ratios gives CH2O.
