We will see that he made 110 kilograms of 9.1% salt solution.
How to get the total mass of the solution?
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.
How to get the concentration?
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:
"He made 110 kilograms of 9.1% salt solution."
