Mass Percentage of Common Salt :
(Mass of Common Salt)/(Mass of Solution) × 100
Given the Mass of Common Salt = 40 grams
Mass of Solution = Mass of Common Salt + Mass of Water
⇒ Mass of Solution = 40 + 320 = 360 grams
Mass Percentage of Common Salt = (40/360) × 100 = 100/9 = 11.1%

Hey there!
Given,
Mass (solute) = 40 gram
Mass (solvent) = 320 gram
Mass (solution) = Mass (solute) + Mass (solvent)
= 40 gram + 320 gram
= 360 gram
∴ Mass % (solution) = [ Mass (solute)/Mass (solvent)] × 100
= [40/360] × 100
= 11.1 %
Hope It Helps You!
