If it takes one second to count two rice grains,calculate the time in years required to count a mole of rice grainrg.

Sagot :

mole is 6,022*10^23 

6,022 * 10^23 /2 (here are seconds) then /60 (minutes), then /60 (hours) /24 (days), then /365 (year) equals 9547818366311516,9965 years

every 4 years there's one day more in a year, so 9547818366311516,9965 /4 ( here are days) then / 365 = 6539601620761,31 years less.

the answer is 9547818366311516,9965 - 6539601620761,31 = 9541278764690755,6865 years to calculate the rice
