Answer: He made 110 kilograms of 9.09% salt solution.
Step-by-step explanation:
Given: Mass of water= 100 kg
Mass of salt= 10 kg
Total mass of the solution: 100kg+10kg= 110 kg
The percent of salt in solution=[tex]\frac{\text{Mass of salt}}{\text{Mass of the solution}}\times100[/tex]
∴The percent of salt in solution[tex]=\frac{10}{110}\times100=9.09\%[/tex]
Therefore, He made 110 kilograms of 9.09% salt solution.
