If 1020 grains are distributed in one sec, 6.023× 1023 grains will be distributed in (6.023 × 1 023 × 1/1 020)=6023 sec = 6023/3600 =1.673 hrs

Q. How much time (in hours) would it take to distribute one Avogadro number of wheat grains if $1 0^{20}$ grains are distributed each second?

16.73

1673

If $1 0^{20}$ grains are distributed in one sec,
$6.023 \times 1 0^{23}$ grains will be distributed in
$\frac{6.023 \times 1 0 ^{23} \times 1}{1 0 ^{20}} = 6023$ $sec = 6023/3600 = 1.673$ $h rs$
