Mass of one atom of the element X is `1.66xx10^(-24) g`. Number of atoms in 1 g of the element is:

A

`1.66xx10^(-24)`

B

`1.66xx10^(24)`

C

`1.66xx10^(-24)xxN_(A)`

D

`6.02xx10^(23)`

Text Solution

Verified by Experts

The correct Answer is:
D
`1 g = (1)/(1.66xx10^(-24)gatom^(-1)) = (10^(24))/(1.66) atom`
`= 6.02xx10^(23) atoms`
