After preparing the graphs, answer these questions:

Experiment $1$

What is the general trend in the solubility of potassium nitrate as temperature increase the general trend of the solubility of potassium increases as the temperature increases.

What amount of potassium nitrate would dissolve at $35C?$

ahout $50((g)1imL{H}_{2}O)$ of $KN{O}_3$ woold dissolve

How much potassium nitrate would dissolve in $50mL$ of water at $25C?$

How much potassium nitrate would dissolve in $135mL$ of water at $20C?$

Experiment $2$

Which is the independent variable, mass or volume?

the independent variable is Volvme.

What is the general trend as mass increases, what happens to the volume? the volume also increases.

What physical quantity is described as the amount of mass divided by the substance?

Graphing: Prepare graphs for the following data using Excel. Remember to follow good graphing protocol when preparing the graph. Also, be sure to answer questions on the basis of the graphs you prepared.

Experiment $1.$

A student measured the solubility of potassium nitrate $(KN{O}_3)$ in $100$ grams of water at varying temperatures. Graph the data from the table below. Remember to graph the independent variable on the $x-$axis. $($Hint: to determine the independent variable in an experiment, think about what the experimenter is really controlling in the experiment $-$ such as in this experiment $-$ what did the experimenter control $-$ the mass or the temperatures used?$)$
