Glucose is $C X_{6} H X_{12} O X_{6}$ ( $M = 180$ ) and sucrose is $C X_{12} H X_{22} O X_{11}$ ( $M = 342$ ) (H = 1, C = 12, O = 16). Which of the following statements is/are correct?

AGlucose has a larger mass percentage of oxygen than sucrose.
BSucrose has a larger mass percentage of hydrogen than glucose.
C $1$ mol of sucrose contains twice as many carbon atoms as $1$ mol of glucose.
DSucrose has a larger mass percentage of carbon than glucose.

Answer: A, C, D

Mass percentages (glucose, sucrose): C 40.00 and 42.11; H 6.67 and 6.43; O 53.33 and 51.46. So sucrose is richer in C, glucose is richer in H and in O. One mole of sucrose has

12

C atoms against

6

for glucose.
