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?

Centimeters cubed, not centimeters

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.

Actually.no. of moles=weight/mol.weight
therefore,weight=moles into*18
=0.083*18
=1.494 g

Isn't 1 mole 1 kg in 1 litre of solution?
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)

your question asks how do u substitute moles to grams, yet your questions are definitely changing grams to moles. so as to alter grams to moles, you're able to be able to desire to DIVIDE by the formula WEIGHT.

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...
