Question

Find the mass of solute , where concentration of the solution is 25%, mass of solvent is 120ml .

formula is :
mass of solute (g)
concentration % =------------------- ×100%
(mass of solvent + mass of solute)

Answer 1

Answer:

Here your answer Friends

Explanation:

We can express the concentrations as mass percent and the units of such concentration is mass(Kg or g) of solute per unit mass(Kg or g) of mixture.

Here mixture is made up of water and sugar.

Given mass of water and sugar is 80 and 25 g respectively.

So the total mass of the mixture is 80 + 25 is equals to 105 grams.

Mass % of sugar(solute) is ( 25/105)*100

=23.81%

Mass % of water (solvent) is (80/105)*100

=76.19%
