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

Answer»

SOLUTION :Avogadro.s number = `6.022 xx 10^(23) and 10^(10)` GRAINS are distributed each second.
`:. """ TIME taken in the distribution of " 6.022 xx 10^(23)` grains
`= (6.022 xx 10^(23))/(10^(10))`
=`(6.022xx10^(23))/(10^(10))xx 1/(3.156xx10^7)` years
`( :. 1 " year " =3.156 xx 10^7 s)`
`=1.908xx10^6` years
