This is so hard i need some it's a response sheet #science

The largest concentration doesn't depend on there being the most water salt but the most salt per unit of water

I would write ratios for each to see how much water there is per teaspoon of salt

Solution 1: 1tsp to 25mL
Solution 2: 1tsp to 25mL
Solution 3: 1tsp to 30mL

So in this case solutions 1 and 2 have the same larger concentration and solution 3 has a smaller concentration

Hope this helps
