Question

If you have 3.8 x 10^24 molecules of O2 at STP how many liters of O2 do you have? Show all work for credit.

Answer 1

Moles= number of molecules/Avogadro’s constant
(3.8 x 10^24) /(6.02 x 10^23)
=6.31229..

Volume=moles*24(molar gas volume under STP)
= 6.31229...*24
= 151.5 dm^3 (units mainly used in the UK)
=. 151.5 litres
