To make a saturated solution 36 gram of sodium chloride is dissolved in hundred gram of water at 293 k find its concentration at this temperature

Mass of solute (sodium chloride) = 36 g (Given) Mass of solvent (water) = 100 g (Given) Then, mass of solution = Mass of solute + Mass of solvent = (36 + 100) g = 136 g Therefore, concentration (mass by mass percentage) of the solution `="Mmmmass of solute"/"Mass of solvent"xx100%` `=36/136xx100%` `= 26.47 %`
