Volume Percentage

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"),,):}

Hydrogen peroxide (H_2 O_2) was first prepared by Thenard by acidifying barium peroxide and removal of excess water by evaporation under reduced pressure. Its strength can be expressed as weigth percentage or as volume percentage . 25% solution by weight means 25 g of hydrogen peroxide are present in 100 g of solution and 25 volume of hydrogen peroxide means that 1 litre of this solution will give 25 L of oxygen at NTP. Calculated the strength of 25 volume solution of H_2 O_2 .
