Calculate the time (in years) required to count one mole of wheat grains If One second is required to count two wheat grain.

Dear Student

2 wheat grains are counted in 1 sec.
6.023 x 1023 wheat grains are counted in 6.023 x 1023/ 2 sec = (6.023 x 1023) / (2 x 60 x 60 x 24 x 365) year = 9.55 x 1015 year

Regards
