Diffine the following mofes of expressing the concentration of a solution? Which of which of these modes are independent of temperature and why ? {:((a),w//w("mass percentage"),(b),V//V("volume percentage")),((c),w//V("mass by volume percentage"),(d),"ppm" ("part per million")),((e),X("mole fraction"),(f),M("molarity")),((g),m("molality"),,):}

Wine W is produced by mixing alcohol X and alcohol Y in the ratio of 4:5 Alcohol X is prepared by mixing two raw materials, A and B in the ratio of 1:2 . Alcohol Y is prepared by mixing two raw materials, B and C, in the ratio of 3:1 . Then the final mixture is prepared by mixing 864 litres of wine W with water. IF the concentration of the raw material B in the final mixture is 50% how much water has been added to wine W
