Question

Gold crystallises in ccp structure the total number of body 291 is 97 gram of gold will be

Answer 1

Hii friend,

# Correct question should be-
Gold crystallises in ccp structure. the total no. of voids present in 197g of gold will be...

# Answer-
3×Avogadro no

# Explaination-
For given gold sample,
No of moles = weight/molecular mass
No of moles = 197/197
No of moles = 1 mol

For CCP structure,
No of voids = 3 × no of atoms in structure.

So, Total no of holes in 1 mole of gold in CCP structure would be 3×Avogadro number.

Hope This helped.
