Question

2. A solution contains 20 gram of sugar mixed with 105 gram of water. What is the concentration of the
solution?

Answer 1

Answer:

Explanation:

Mass of solute = 20

Mass of solvent = 105

Mass of solution = mass of solute + mass of solvent

= 20 + 105 = 125

We know that

Concentration of solution =

Mass of solvent/ (mass of solute + mass of solvent) × 100

{20 / (20+105)} × 100

{20/125}×100

16%

Thus,

The concentration of sugar solution is 16% (by mass %)
