Answer 1

Explanation:

In 380 g common salt solution contain 40 g of common salt. Calculate the concentration in term of mass by mass percentage of the solution

Answer 2

Given: In 380 g common salt solution 40 g of common salt.

To find: Concentration in terms of mass by mass percentage

Explanation: Mass of salt solution= 380 g

Mass of common salt= 40 g

Mass percentage is the unit of concentration which signifies the mass of solute per mass of solvent.

Mass percentage of common salt= Mass of common salt * 100 / Mass of solution

= 40*100/380

= 10.52%

Mass percentage of solute= 100- mass percentage of common salt

= (100-10.52)%

= 89.48%

Therefore, the mass percentage of common salt in the solution is 10.52% and the mass percentage of solute is 89.48%.
