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

 

Answer

Here,

  • Solute is sodium chloride
  • Solvent is water

 

Now,

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))   × 100%

                                         = (36/136) × 100%

                                         = 9  × 100/34 %

                                          = 26.47 %
