A weight lifter, after weight lifting exercises. drinks 500 mL of 9% glucose (mol. Mass 180) solution. The number of glucose molecules consumed by him are

A

`1.5xx10^23`

B

`3.0xx10^23`

C

`4.5xx10^23`

D

`6.023xx10^23`

Text Solution

Verified by Experts

The correct Answer is:
A
Mass of glucose consumed = 9 x 5 =45 g
`therefore` No of glucose molecule consumed =`45/180xx6.02xx10^23=1.5xx10^23`
