Asked by Asmera
                5.85g of sodium chloride is dissolved in 250mL of solution. Calculate: a)the molarity of the solution b)the mass percentage of the solute. can we use the given volume(i.e,250mL as total volume of the solution or volume of water in this problem?

    The problem tells you that the total solution is 250 mL. However, in the absence of more information I think you must use it both ways.
mols NaCl = grams/molar mass, then M = mols/L soln.
% w/w = (g solute/(250+5.85)*100 = ?
Technically I don't think you can calculate % w/w since you don't know the density of the solution.
