Question

Solute of 20 gram dissolve in 300 gram of solution .concentration in mass by mass percentage

Answer 1

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 ) = 180g

.°. Total Mass Of The Solution= 180g + 20g

= 200g

Therefore, mass by mass percentage of the solution = Mass of the solute / Total mass of the solution × 100

i.e, 20/200 × 100

=10% Ans.
