Number of atoms in 558.5 gm Fe (At.wt of Fe = 55.85 g `mol^(-1)`) is

A

Twice that in 60 g carbon

B

`6.023xx10^(22)`

C

Half that in 8g He

D

`558.6xx6.023xx10^(23)`

Text Solution

Verified by Experts

The correct Answer is:
A
moles `=(558.5)/(55.85)=10=6xx10^(24)` atoms
`60g C=(60)/(12)=5` moles
`therefore` atoms = twice in 60 gc
