Iron has density of` 7.86 gcm^(-3)` and an atomic mass of 55.85 u. The volume occupied by 1 mol of Fe is

A

`22.8 cm^3 "mol"^(-1)`

B

`7.11cm^3 "mol"^(-1)`

C

`3.64 xx 10^24 cm^3 "mol"^(-1)`

D

`5.26 cm^3 "mol"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
Molar volume = molar mass/density
` = (55.85 g "mol"^(-1) )/(7.86 g cm^(-3) ) = 7.11 cm^3 "mol"^(-1)`
