Total number of tetrahedral and octahedral voids in 0.5 mol of a compound forming hcp structure are :

Answer»

`6.022 xx 10^(23)`
`3.011 xx 10^(23)`
`9.033 xx 10^(23)`
`4.516 xx 10^(23)`

Solution :for 1 MOL of a COMPOUND, number of TETRAHEDRAL and octahedral voids = `2+1=3`
`:.` No. of voids `= 3 xx 0.5 xx 6.022 xx 10^(23)`
`= 9.033 xx 10^(23)`
