Question

A solution contains 50grm of common salt in 250grm of water .calculate mass percentage​

Answer 1

Explanation:

Answer: The mass percent of common salt is 20 %.

Explanation:

A solution contains both solute and solvent. A solute is a substance which is present in smaller proportion and solvent is a substance which is present in larger proportion.

We are given:

Mass of common salt (solute) = 50 g

Mass of water (solvent) = 200 g

To calculate the mass percent of common salt, we use the equation:

Mass of solution = (50 + 200) = 250 g

Mass of common salt = 50 g

Putting values in above equation, we get:

Hence, the mass percent of common salt is 20 %.
