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

Answer

`1.9096xx10^(6)" years"`

Explanation

`"Avogadro number "=6.022xx10^(23)`
`10^(10)` grains are distributed in = 1 sec
`6.022xx10^(23)` grains would be distribtued in
`=(6.022xx10^(23))/(10^(10))" sec"`
`=(6.022xx10^(23))(10^(10)xx3600xx24xx365)`
`=1.9096xx10^(8)" years"`.
