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`

Text Solution

Verified by Experts

The correct Answer is:
A
0.833 mole of carbohydrate has hydrogen = 10 g
` therefore ` 1 mole of carbohydrate has hydrogen `= (10)/( 0.833) xx 1 = 12` .
` therefore ` Molecular formula of hydrocarbon = `C_6 H_(12) O_6`
