`0.1 mol` of a carbonhydrate with empirical formula `CH_(2)O` contains `1 g` of hydrogen. What is its molecular formula?

A

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

B

`C_(3)H_(6)O_(3)`

C

`C_(4)H_(8)O_(4)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
A
`0.1` mol of carbohydrate contains `1 g H`, thus, `1` mol of carbohydrate will contain `10 g H`. In other words, `1` molecule contains `10 "amu" H`. The only formula that confirms is `C_(5)H_(10)O_(5)`.
