The weight of one molecule of a compound...

The weight of one molecule of a compound `C_(60)H_(12)` is

A

`1.3xx10^(-20)`g

B

`5.01xx10^(-21)`g

C

`3.72xx10^(23)`g

D

`1.4xx10^(-21)`g

Text Solution

Verified by Experts

The correct Answer is:
D
Wt. of one molecule
`= ("Mol mass of" C_(60)H_(122))/(6.023xx10^(23))`
`= ((12xx60)+122)/(6.023xx10^(23)) = (842)/(6.023xx10^(-23))`
`=1.4xx10^(-21)g`
