17. Which solution is more concentrated?
Solution 1:
500 mL of water
100 g of salt
Solution 2:
500 mL of water
90 g of salt

Solution 1.

Explanation:

We can find the concentration of a solution by looking at the ratio of the components.

In the first solution, there is a 500 mL:100g ratio. In the second, there is a 500mL:90g ratio. The greater ratio, or the ratio with a greater amount of solute in proportion to the water, is the first.
