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




The solute is sodium chloride and,

The solvent is water


Mass of solute = mass of sodium chloride = 36g

Mass of solvent = mass of water = 100g

Mass of solution = Mass of solute + Mass of solvent

                           = 36g + 100g

                            = 136g


Concentration of solution = (Mass of solute (g)/Mass of solution(g)) x 100%

                                         = (36g/136g) x100%

                                         = 9x100/34 %

                                          = 26.47 %
