Question

A solution contains 25g of sugar in 100g of water. Calculate the concentration of this solution.

Answer 1

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

Answer 2

Given:

A solution contains 25g of sugar in 100g of water.

To find:

We have to find the concentration of the solution.

Solution:

To determine the concentration of the solution we have to follow the below steps as follows-

The amount of solute that is sugar in the solution is 25 grams.

The amount of solvent that is water is 100 grams.

Thus the total amount of solution is 100+25=125 grams.

Thus, the concentration of the solution can be given as-

$\frac{25}{125} \times 100 \\ = 20\%$

The concentration of the solution is 20%.
