alleryEmpirical formula of glucose (C6H12O6) is:
ACHO
BCH2O
CC2H4O2
DC3H6O3
Answer & Solution
Correct answer: B. CH2O
1. Divide all subscripts by their highest common factor.
2. C:H:O = 6:12:6, dividing by 6 gives 1:2:1.
3. So the empirical formula is CH2O.
4. The molecular formula is six times the empirical formula.
