Question

To make a saturated solution, 20g of salt is dissoved in 80g of solvent. Find its concentration?

Answer 1

Explanation:

Mass of solute = 20 g

Volume of solution = 500 ml

Mass by volume percentage =

Volume of solution

Mass of solute×100

=

500

20×100

=4%

Answer 2

Answer :-

20%

Explanation :-

Given :

Mass of the solute (salt) = 20g

Mass of the solvent = 80g

We know,

Mass of solution => Mass of solute + Mass of solven

=> 20g + 80g

∴ 100g

To Find :

Concentration = ?

Solution :

We know,

$\sf{}Mass\ percentage\ of\ solution=\dfrac{Mass\ of\ the\ solute}{Mass\ of\ the\ solution}\times 100$

Put their values and solve it.

$\sf{}:\implies \dfrac{20}{100}\times100$

$\sf{}:\implies \dfrac{20}{1}\times1$

$\sf{}\therefore 20\%$

Therefore,concentration is equal to 20%
