Question

Some salt is dissolved in 135 g of water to form 150 g solution. Concentration of solution will be
a. 90%
b. 10%
c. 15%
d. None of these​

Answer 1

Answer:

b. 10%

Explanation:

Given,

Solvent: 135g

Solution: 150g

To find:

(i) solute

(ii) concentration

Procedure:

Solute= Solution-Solvent

[since solute+solvent=solution]

Solute= 150g-135g

Solute= 15g

Concentration= Solute × 100

Solution

= 15g/150g ×100

= 10%

Hope it helps!
