How much time would it take to distribute one Avogadro number of wheat

1.	How much time would it take to distribute one Avogadro number of wheat grains, if 10^(10) grains are distributed each second ?
Answer» SOLUTION :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 !).
