An element (density =`6.8gcm^(-3)` ) occurs in bcc structure with cell edge of `290"pm"` .Calculate the number of atoms present in `200g` of the element:-

Text Solution

Verified by Experts

The correct Answer is:
`24.12 xx10^23` atoms
Calculate the atomic mass, M. Then M grams contains `6.023xx10^23` atoms. Calculate atoms present in 200 g.
