Answer:
Solute in solution- 25g
solvent in solution-100g
total solution - 25+100=125g
mass percentage of concentration= solute/total solution ×100
=25÷125 ×100
= 20percent
hence concentration of this solution. is 20% ans
i hope its help you.

Answer:
The solubility is expressed in grams/100 ml.
Since solubility of sugar is 25g, it means that 25g of sugar can be dissolved in 100g of water.
This implies that 50g of sugar can be dissolved in 200ml of water. So out of the 70g which is added, only 50g of sugar dissolves.
Thus,
Weight of solute=50g
Weight of solution = 200+50= 250g
Concentration (w/w) = (50/250)x100 =20 %
Explanation:
i think so this answer is correct
