Weight of one atom an element is `6.44 xx 10^(-23) g`. Calculate g atom of elements in `40 kg`.

A

`10^(2)`

B

`10^(3)`

C

`10^(4)`

D

`10^(5)`

Text Solution

Verified by Experts

The correct Answer is:
B
`g`-atomic weight
`=6.644xx10^(-23)xx6.023xx10^(23)=40 g`
`:. g "atom in" 40xx10^(3)kg=(40xx10^(3))/(40)=10^(3)`
