Q about atoms and moles ?

Question

The approximate population of Earth is 5.7 billion people. If all people were pea pickers and pea counters, then how long would it take for the Earth's population to count out one mole of peas at the rate of one pea per second, working 24 hours per day, 365 days a year?

Answer 1

you would divide avogadro's number by 5.7 billion, to get the answer in seconds.

about 10^14 seconds

Answer 2

One potato, two potato, three potato, four......

OK, 1 mole of peas= 6.02x10^23 peas.

So if we have 5.7x10^9 people, that means each person spends about 1.05x10^14 seconds counting peas.

For lazy people, 1 year= pi x 10^7 seconds (appx)

So it would take about 3.5 x 10^6  YEARS.  

Hopefully some people could count fast so others could take some time off to repopulate the Earth.   Any volunteers?
