Find the minimum volume of hot water needed to dissolve 100 mg of salicylic acid. Can someone help me how to start this out? I would greatly appreciate it.

The data is
[temp] [amount of salicylic acid per 100 ml water, g]
0 0.10
10 0.13
25 0.23
50 0.63
75 1.8
90 3.7

If you call hot water 90 degrees C, then
100 mL H2O x (0.10 g/3.7g)= ??

Then the minimum volume of hot water then is 2.70mL

That's what I get. I don't know what your prof calls hot water but the minimum volume of water, of course, is at the highest temperature.
