Question

36 g. of sodium chloride is dissolved in 100 g. of water at 300 Kelvin, find the concentration of mass by mass percent

Answer 1

Mass of Sodium chloride =36g
Mass of Water = 100g
Total mass of solvent = 136g

Mass/mass %
= mass of solute /mass of solvent * 100
= 36 / 136 *100
= 26.4705%



Ans: 26.47%
