Question

A crystalline solid of a pure substance has a Face centered cubic structure with cell edge of 400 pm . If density = 8g/cm, then the number of atoms present in 256g of the crystal is N *10 ^24 . Find the value of N

Answer 1

Answer:

A crystalline solid of pure substance has a face-centred cubic structure with a cell edge of 400 pm. If the density of the substance in the crystal is 8 g cm

3

then the number of atoms present in 256 g of the crystal is $$N\times . The value of N is ... .
