3. what scientific value does the slope of a line created by graphing mass versus volume represent?
Answer
Brief Explanations:
The slope of a mass - volume graph represents density. Density is defined as mass per unit volume ($\rho=\frac{m}{V}$), and on a graph of mass ($m$) versus volume ($V$), the slope $\frac{\Delta m}{\Delta V}$ gives the density of the substance.
Answer:
Density
