Question

find the mass percentage of the solutionwhrn 45g of nacl is dissolved in 100 g of water​

Answer 1

Explanation:

Mass of solute i.e, for the sodium chloride =58.5g

Mass of solvent i.e, for the water=100g

Mass of solution=58.5+100=158.5g

The concentration of solution in terms of mass percentage is given as,

 

                           =Mass of solute/Mass of solution ×100

                            =58.5/158.5×100

                             

                               =36.9%
