### #E5 part b)

When finding how many years it would take to pick one mol of peas, am I supposed to start off the calculation by using my answer from part a? Because technically the moles of people is the same as the moles of peas if everyone picked one pea? I know how to get from seconds to years, but I'm stuck on what to do before I use peas/sec. Thank you :)

I am not entirely sure, but I think you could use the moles of people, or include the conversion you did in part a in your answer. You would need the moles of people in order to convert to seconds because you have to cancel the moles of peas to have an answer in time units.

You need to include the answer achieved in part a in the part b calculation.

So, 1 / (1.2 x 10^-14 mol) represents the time in seconds.

All that needs to be done after is a conversion to time in years. Hope this helps!
