#### Question

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

#### Solution 1

Avogadro number = 6.02 × 10^{23}

Thus, time required

`= (6.02 xx 10^(23))/10^10 s`

`= 6.02 xx 10^23 s`

`= (6.02 xx 10^23)/(60xx60xx24xx365)` year

`= 1.909 xx 10^6` year

Hence, the time taken would be `1.909 xx 10^(6)` year

#### Solution 2

Time taken to distribute `10^10` grain =1 s

Time taken to distribute = `6.022 xx 10^23 "grain"`

`= (1 s xx 6.022 xx 10^23 "gain")/(10^10 "grain")`

=` (6.022 xx 10^13)/(60xx60xx24xx365) ` = `1.9 xx 10^6` yr

Is there an error in this question or solution?
