The amount of `""_(92)"U"^(235)` in a sample of 20 g of naturally occurring uranium will be nearly _______ .

A

10 g

B

14 g

C

3.36 g

D

0.14 g

Text Solution

Verified by Experts

The correct Answer is:
D

Naturally occurring uranium contains only 0.7% of `""_(92)"U"^(235)`. Thus , the amount of `U^(235)` in a 20 g sample
`= 20 xx(0.7)/(100)`
= 0.14 g
