Ds has the attached question.
We know the answer is 0.5.
We know the method and the equation n =c times v
But for the life of us, we cannot get to the correct answer. We always end up with 80. (Or 20)
Help!
It has driven dc nuts for hours and myself at least an hour since I got home from work!

The question gives a concentration in g/dm3 but asks for the answer in mol/dm3. Have you converted 20g/dm3 into mol/dm3? Use n=m/GFM
