Answer:5.55%
Explanation:
A solution contains 20g of sugar dissolved in 180g water calculate the concentration in tems of mass by mass percentage of solution.
Ans. Sugar dissolves = 20g
Water ( Mass ) = 340g
.°. Total Mass Of The Solution= 340g + 20g
= 360g
Therefore, mass by mass percentage of the solution = Mass of the solute / Total mass of the solution × 100
i.e, 20/360 × 100
=5.55% Ans.
