Answer» A solution contains a SOLID solute (sugar ) DISSOLVED in a liquid solvent (water),so we have to calculate the concentration of this solution in terms of the mass PERCENTAGE of solute (sugar ) we, Know that :Concentration of solution =Mass of soluteMass of solution ×100here, Mass of solute (sugar )=30gAnd ,Mass of solvent (water)=370gSo ,Mass of solution = Mass of solute + Mass of solvent=30+370=400 gNow ,Putting the values Of mass of solute and mass of solution in the above formula formula ,WE GET :Concentration of solution =30400×100=3047.5 per cent (or 7.5% )THus , the concentration of this sugar solution is 7.5 per cent (or that it is a 7.5 % sugar solution). |
