How many moles in a gram of solution/liquid?

Is there a mole in every gram of solution? or is there another way of weighing how many moles in a solution/liquid?


I need 0.083 moles of water, how much is that in centimeters or grams?

No, there is not a mole in every gram of solution. It all depends on the molecular weight, which depends on the identity of the elements involved.





Water's molecular weight is 18 g/mole, so 0.083 moles of water would weigh 1.49 grams. Given water's density is roughly 1 g/ml, that would also be 1.49 ml or 1.49 cm^3.

I can't remember -- but you should see the damage just a single mole did to my lawn last year!





(PS as is probably evident I was rubbish at Chem..and now TheOnlyBeldin has made me feel quite stupid...I'll stick to subjects I feel happier with in future)

Reply:You need .083 moles of water?





(.083 moles H2O) (18 grams H2O/ mol of H2O) = (Moles cancel out) 1.49 grams H2O





If you want a molar concentration of .083 M, that's different...
Reply:Actually.no. of moles=weight/mol.weight


therefore,weight=moles into*18


=0.083*18


=1.494 g
