Answer:
It takes 1.9 years to distribute all the grains.
Explanation:
In one second, grains of wheat are distributed.
We are supposed to find the time it would take to Distribute Avogadro number of grains.
1 avogadro number = 6.022
Number of grains distributed in 1 day = 86400
= 8.64
Number of grains distributed in 1 year= 8.64
= 3.1536
Time taken =
=
= 1.9
