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

(N/A) The Avogadro number is $6.02 \times 10^{23}$.
The time required in seconds is calculated as:
$\text{Time} = \frac{6.02 \times 10^{23}}{10^{10}} \ s = 6.02 \times 10^{13} \ s$.
To convert this into years:
$\text{Time in years} = \frac{6.02 \times 10^{13}}{60 \times 60 \times 24 \times 365} \ \text{years} \approx 1.909 \times 10^{6} \ \text{years}$.
Hence,the time taken would be approximately $1.909 \times 10^{6} \ \text{years}$.
