how many unit cells are present in a cubic shaped ideal crystal of Nacl of mass 1.0 gram
1 Answer
PRAJWAL
its nearly equal to 8.2*10^21, Reason mol.massNaCl is 36.5g and in ccp each unit cell contains 2 atoms .therefore calculate the no.of atoms in 1g of NaCl ie.6.022*10^23/36.5. apply the same logic i unit cell 2 atoms then the above value how much atoms and you woud get the answer.
