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

Options

A. `6.022 xx 10^(23)`
B. `3.011 xx 10^(23)`
C. `9.033 xx 10^(23)`
D. `4.516 xx 10^(23)`

Answer

C

Explanation

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)`
