okay all of you are confusing me! i learnt it that moles was avogrado constant which means the amount of particles in a substance as in carbon atoms in exactly 12g of the carbon 12-isotope. the formula is n= m/Mr or n=c*v(in cm3)/1000 or c*v(dm3) finally, n=v(dm3)/24.0 or n=v(cm3)/24000

All of what you have said here is true, but mostly irrelevant, you arn't being asked to calculate how many molecules of solvent there are, merely the weight of what has been dissolved. So basically, here is a full solution, because you are getting yourself confused:
