Weight of one atom an element is `6.44 xx 10^(23) g`. Calculate g atom of elements in `40 kg`.

Text Solution

Verified by Experts

Weight of 1 atom of element `= 6.644 xx 10^(-23) g`
`:.` Weight of `N` atom of element
`= 6.644 xx 10^(-23) xx 6.023 xx 10^(23)`
`=40`
`:' 40 g` weight of element has `1 g` atom
`:' 40 xx 10^(-23) g` weight of element
`(40 xx 10^(3))/(40) = 10^(3) g` atom
