Question

0.833 mole of a carbohydrate, with empirical formula CH 2 O has 10 g of hydrogen. Molecular formula of carbohydrate is (A) C 6 H 12 O 6 (B) C 3 H 5 O 3 (C) C 3 H 10 O 5 (D) C 3 H 4 O 3

Tardigrade Admin · Accepted Answer

0.833 mole of carbohydrate has hydrogen =10 g ∴ 1 mole of carbohydrate has hydrogen =(10/0.833) × 1=12 ∴ Molecular formula of hydrocarbon = C 6 H 12 O 6

Q. $0.833$ mole of a carbohydrate, with empirical formula $C H_{2} O$ has $10 g$ of hydrogen. Molecular formula of carbohydrate is

$C_{6} H_{12} O_{6}$

$C_{3} H_{5} O_{3}$

$C_{3} H_{10} O_{5}$

$C_{3} H_{4} O_{3}$

$0.833 m o l e$ of carbohydrate has hydrogen $= 10 g$

$∴$ 1 mole of carbohydrate has hydrogen $= \frac{10}{0.833} \times 1 = 12$

$∴$ Molecular formula of hydrocarbon $= C_{6} H_{12} O_{6}$
