Answer 2

Given :

Mass of sugar in solution (m) = 40 gm

Mass of water = 100

To Find :

The concentration in terms of mass by mass percentage of solution.

Solution :

Mass of solute = 40 gm

Mass of solvent = 100 gm

Mass of the solution = (100 + 40) gm = 140 gm

Mass percentage of the solute in the solution = $\frac{Mass of Solute}{Mass of Solution}$ × 100%

                                                                            = $\frac{40}{140}$ × 100%

                                                                            = 28.57%

Therefore, the concentration of solute in the solution in terms of mass percentage is 28.57%.
