Detailed Solution

Given:  Mass of solute = 40g

               Mass of solute= 320g

Mass of solution   =  Mass of solute + Mass of solvent

                                  =40 +320

                                  =360g

Mass by mass percentage of solution =Mass of soluteMass of solution × 100

                                                                           = 40360× 100   

                                                                           =1009

                                                                           = 11.1%

The mass by mass percentage of the given solution is 11.1%
