Question

If 10¹⁰ wheat grains are spread out in second then how much time is required t spread wheat grains equivalent Avogadro's number?

Answer 1

If 10¹⁰ wheat grains spread in 1 second. 

Then time required for 6.022 × 10²³ grains

\( = \frac{1\ s\times 6.022\times 10^{23}}{10^{10}}\)

\( = \frac{6.022\times 10^{13}}{60\times 60\times 24\times 365}\)

= 1.91 × 10⁶ years
