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

A

(a)`10^(3) g` atom

B

(b)`10^(2) g` atom

C

(c )`10^(4) g` atom

D

(d)`10 g` atom

Text Solution

Verified by Experts

The correct Answer is:
a
Weight of Avogadro number `(N)` of atoms of the element
`=6.644xx10^(-23)xx6.023xx10^(23)`
`=40 g`
`40 g`=weight of 1 g atom
`:. 40xx10^(3) g`= weight of `10^(3) g atom`
