Question

A solution is prepared by dissolving 25g of sugar in 175g of water. Calculate the concentration of sugar solution

Answer 1

given, mass of solute = 25g

mass of solvent= 175g

so , mass of solutw = 25+175 = 200g

thus concentration of solution = (

mass of solute × 100/ mass of solution)

= 25×100/ 200

= 2500/200

=12.5%

Answer 2

Explanation:

20%

Solubility is 25,so 25 gm in 100gm water

So In 200g of water 50 gm can be dissolved but 70gm is dissolved

So only 50gm dissolves and 20gm remains

Tot mass of final solution is 250gm

So conc of filtrate. Is 50/250*100 which is 20%
