Question

a) To make a saturated solution 55g of Nacl is dissolved in 120g of water
at 35° C. Find its concentration at this temperature.​

Answer 1

Answer:

       Mass of solute =55 g                                                                        

        Mass of solvent =100 g  

        Mass of solution= 100+55

                                  =155 g

         concentration of solution = (mass of solute / mass of solution) x 100

                                                         = (55/150 ) x 100

                                                         =   272. 72 percentage

Answer 2

Answer:

Mass of solute =55 g Mass of solvent =100 g

Mass of solution= 100+55 =155 g

concentration of solution = (mass of solute / mass of solution) x 100

= (55/150 ) x100 = 272.

72 %.
