Calculate atomic volume of sodium 9atomi...

Calculate atomic volume of sodium 9atomic weight =23). Density of sodium=0.972g`*mL^(-1)`.

Text Solution

Verified by Experts

In case of monoatomic eleements (like Na), volume of 1 gram-atom is called its atomic volume.
1 gram-atom Na=23g of `Na` (`because` atomic mass of Na=23)
`therefore`Atomic volume of sodium`=("gram-atomic mass")/(density)`
`=(23g)/(0.972g*mL^(-1))=23.66mL`
