question_answer 1)

How much time would it take to distribute one Avogadro's number of wheat grains if \[{{10}^{10}}\] grains are distributed each second?

Answer:

\[{{10}^{10}}\]grains are distributed in 1 second \[\therefore \]\[6.023\times {{10}^{23}}\]grains will be distributed in \[\frac{1}{{{10}^{10}}}\times 6.023\times {{10}^{23}}\sec ,i.e.,6.023\times {{10}^{13}}\sec .\]
