An atom of an element weighs `6.644 times 10^(-23)` g. Calculate g atoms of element in 40 kg-

Text Solution

Verified by Experts

Weight of 1 atom of element = `6.644xx10^(-23)g`
`therefore` Weight of N atoms of element
`=6.644xx10^(-23)xx6.023xx10^(23)=40`
Since 40 g weight of element has a 1 g-atom.
`therefore 40xx10^(3)g` weight of element has `=(40xx10^(3))/(40)`
`=10^(3)` g-atoms
