to find the number of mole with mass and Mr and Ar.
Moles=mass/Ar or Mr
to find number moles with volume
moles= volume in dm3 / 24
if the volume was in cm3 then devide it by 10000. (to do any calculations with volume in it, the volume must be in dm3)
volume in dm3= volume in cm3/1000

moles= volume in dm3 x concentration
