Question

a solution contains 60g of common salt in 240g of water. calculate the concentration in term of mass by mass percentage of solution

Answer 1

Answer:

Explanation:

mass of solute = 60 g

mass of solvent =240g

mass of solution = 60g

Mass of solute + mass of solvent = 60+240=300g

concentration of solution = 60/300 x 100

= 1/5 x 100

= 20%

Answer 2

Given:

A solution contains 60g of common salt in 240g of water.

To find:

We have to find the concentration of solution.

Solution:

To determine the concentration of the solution by mass percentage we have to follow the below steps as follows-

The amount of solute that is common salt is 60 grams.

The amount of solvent that is water is 240 grams.

Thus, the mass of the solution is 240+60=300 grams.

Thus the concentration of the solution by mass percentage is given as-

Concentration= mass of solute/mass of solution×100.

Concentration=60/300×100

Concentration=20%

The concentration of the solution is 20%.
