How much time (in hours ) would it take to distribute one avogardo 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

Time taken to distribute `10^20` grains = 1 second
Time taken to distribute `6.022 xx 10^23` grains
` = (1)/(10^20) xx 6.022 xx 10^23 ` seconds
` = (6.022 xx 10^23)/(10^20 xx 60 xx 60) ` hours
= 1.673 hours
