1.	10% solution is prepared by dissolvingcomponent A to 20gm of watercalculate weight or mass of componentA.
Answer» Required Answer:- We have:- Mass of the SOLVENT = 20 gm % composition of the solution = 10% To FinD:- WEIGHT or mass of the component A or the SOLUTE of the solution? Step-by-Step CALCULATION:- Let the mass of the solute be x. Concentration of the solution by mass-mass % is: Mass of the solute / Mass of solution × 100. Then: ⇒ x / 20 + x × 100 = 10 ⇒ x / 20 + x = 1/10 Cross multiplying, ⇒ 10x = 20 + x ⇒ 9x = 20 ⇒ x = 20/9 = 2.22 g (approx. $)$ Hence:- The required mass of solute or component A is 2.22 g (approx.)

Required Answer:-

We have:-

Mass of the SOLVENT = 20 gm
% composition of the solution = 10%

To FinD:-

WEIGHT or mass of the component A or the SOLUTE of the solution?

Step-by-Step CALCULATION:-

Let the mass of the solute be x. Concentration of the solution by mass-mass % is: Mass of the solute / Mass of solution × 100.

Then:

⇒ x / 20 + x × 100 = 10

⇒ x / 20 + x = 1/10

Cross multiplying,

⇒ 10x = 20 + x

⇒ 9x = 20

⇒ x = 20/9 = 2.22 g (approx. $)$

Hence:-

The required mass of solute or component A is 2.22 g (approx.)
