Explanation:

Answer: The mass percent of common salt is 20 %. Explanation: A solution contains both solute and solvent.

Answer 2

Given,

A solution contains 50g of common salt in 200g of water.

To Find,

The concentration in term of mass by mass percentage of the solution.

Solution,

Amount of solute i.e. common salt = 50 grams

Amount of solvent i.e. water = 200 grams

Total mass of solution = mass of solvent + mass of solute

= 200 + 50

= 250 grams

Formula for mass by mass percentage →

$\dfrac{Mass\:of\:solute}{Mass\:of\:solution}\times100$

= $\dfrac{50}{250}\times100$

= 20%

Therefore, the mass by mass percentage of the concentration of the solute in the solution is 20%.

Knowledge Bytes:

→ A solution contains a solute and a solvent.

→ A solute is the substance present in the solution in smaller amounts in proportion with solvent. It is usually a solid.

→ A solvent is the substance present in the solution in larger amounts in proportion with the solute. It is usually a liquid.

→ The concentration of a solution refers to the amount of solute present in a solution at a particular time.
