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

Text Solution

Verified by Experts

1 Avogadro no. are wheat grains `= 6.022xx10^(23)` now, `10^(10)` grains are distributed time in = 1 sec.
`therefore 6.022xx10^(23)` grains would be distributed time in
`= (6.022xx10^(23)xx1s)/(1xx10^(10))=6.022xx10^(13)` sec.
`= (6.022xx10^(13)s)/(60xx60xx24xx365 "s year"^(-1))`
`= (6.022xx10^(13))/(0.6xx0.6xx2.4xx3.65xx10^(7))` year
`= 1.90957xx10^(6)` year `~~` 1909570 year
19 Lakh 9 Thousand five hundred seventy years. (Think about it : How big value Avogadro number is !).
