Q14 of 23 Page 152

How much time would it take to distribute one Avogadro number of wheat grains, if 1010 grains are distributed each second?

We know that Avogadro number = 6.02 × 1023.

Given that rate of distribution = 1010 grains per second.


Thus, time required to distribute one Avogadro number of wheat grains: -


= Avogadro number / rate of distribution



= 6.023 x 1013 s



=1.909 x 106 years


Hence, the time taken to distribute one Avogadro number of wheat grains is 1.909 x 106 years.
