We will see that he made 110 kilograms of 9.1% salt solution.
<h3>
How to get the total mass of the solution?</h3>
The total mass will be just the sum of the mass of water and the mass of salt, we will get:
100kg + 10kg = 110kg
So the mixture has a mass of 110kg.
<h3>How to get the concentration?</h3>
The concentration is the quotient between the mass of the salt (10kg) and the total mass of the mixture, and we can multiply that by 100% so we get a percentage.
C = (10kg/110kg)*100% = 0.091*100% = 9.1%
This means that the concentration of the mixture is 9.1%
Concluding, the final sentence is:
<em>"He made 110 kilograms of 9.1% salt solution."</em>
