Q 3. To make a saturated solution, 36 g of sodium chloride is dissolved in 100 g of water at 293 K. Find its concentration at this temperature.
Given that,
Mass of solute (sodium chloride) = 36 g =
Mss of water (as a solvent) = 100 g =
Therefore, the total mass of solution = 100 + 36 = 136 g =
According to question,
Concentration =
%
Hence the concentration of the solution at 293 K is 26.47%
