When plotting a solubility curve, would I not be showing the temp in one of the x y variables? Convert your grams/10 mL values to grams/100 mL values and plot a
solubility curve for potassium chloride. The horizontal axis is the temperature
scale from 20 to 80C using 10-degree intervals, and the vertical scale is the
solubility in g/100 mL

Thank you for the opportunity to help you with your question!

The temperature is plotted on the x-axis whereas the grams/100ml is plotted at the y-axis. Just a little tip on this one, label the x-axis with a 10 degrees celcius difference starting at 0,10,20...onwards up to 100 degrees celcius. For the y-axis, use a 10g/100ml difference such that it appears as 0,10,20...onwards up to 100g/100ml.

Please let me know if you need any clarification. I'm always happy to answer your questions.
