How much time (in hours) would it take to distribute one Avogadro number of wheat grains, if `10^(20)` grains are distributed each second ?

A

0.1673

B

1.673

C

16.73

D

167.3

Text Solution

Verified by Experts

The correct Answer is:
B
If `10^(20)` grains are distributed in 1s, `6.023 xx 10^(23)` grains will be distributed in
`(6.023 xx 10^(23) xx 1)/(10^(20)) = 6023 s = 1.623` hr
