Solution

Given: Mass of solute (salt) = 40 g
Mass of solvent (water) = $320 g$
Step-1: finding the mass of the solution:
$Mass of solution = Mass of solute + Mass of solvent$
$= 40 g + 320 g = 360 g$
Step-2: Substituting the values in the formula, we get
$M a s s P e r c e n t a g e o f S o l u t i o n = \frac{M a s s o f s o l u t e}{M a s s o f s o l u t i o n} \times 100$
$M a s s P e r c e n t a g e o f S o l u t i o n = \frac{40 g}{360 g} \times 100 = 11.1 %$
Conclusion: Therefore, the concentration of this solution is $11.1 %$ by mass.
