Answer 2

Answer:

Explanation:

Mass of solute (sodium chloride) = 40 g

          Mass of solvent (water) = 120 g

        Concentration = (mass of solute/ mass of solution) * 100

                                  = (40/120)*100

                                  = 3*100

                                  =  300
