`0.0833 `mol of carbohydrate of empirical formula `CH_(2)O` contain `1 g ` of hydrogen. The molecular formula of the carbohydrate is

A

`C_(5)H_(10)O_(5)`

B

`C_(3)H_(4)O_(3)`

C

`C_(12)H_(22)O_(11)`

D

`C_(6)H_(12)O_(6)`

Text Solution

Verified by Experts

The correct Answer is:
d
`:' 0.833` mole carbohydrate has hydrogen `=1g`
`:. 1 mol` carbohydrate has hydrogen
`=(1)/(0.833)=12g`
Empirical Formula `(CH_(2)O)` has hydrogen `=2g`
Hence `n=(12)/(2)=6`
Hence molecular formula of carbohydrate `=(CH_(2)O)_(6)`
`=C_(6)H_(12)O_(6)`
