A student measured the maximum mass of salt that can dissolve in 100 mL of water at five different temperatures. Which variable should go on the y-axis?

the volume of water

the temperature of water

the mass of salt

the mass of water

the mass of salt

Explanation:

In an experiment, we have an independent variable and dependent variable. The independent variable is the variable that is manipulated to cause changes in other variable while the dependent variable is the variable that responds to the changes made to the independent variable and is measured.

In this case of experiment, the mass of the salt is the DEPENDENT VARIABLE while the different temperatures is the INDEPENDENT VARIABLE. In a graphical representation, the independent variable is always plotted on the x-axis or horizontal axis while the dependent variable is always plotted on the y-axis or vertical axis.

Since the dependent variable is the mass of the salt, it should be plotted on the y axis.
