Problem: Calculate the mass percentage of Na2 SO4 in a solution containing 10.6 g Na2 SO4 in 485 g water.

FREE Expert Solution

We are asked to calculate the mass percentage of Na2SO4 in a solution containing 10.6 g Na2SO4 in 485 g water.


To find the mass percent of the solution, we're going to use the mass percent formula shown below:

mass percent=mass componenttotal mass×100


Since we are dealing with a solution, we can rewrite the equation as:

% mass=mass solutemass solution×100


We will first determine the total mass of the solution then calculate the mass percent.

Step 1: Calculate the total mass

Step 2: Calculate the mass percentage
