# How do you determine the density from a graph of volume and mass?

Sep 19, 2016

From the slope of the line with mass on the y axis and volume on the x axis

#### Explanation:

Density is Mass over Volume $D = \left(\frac{M}{V}\right)$

Slope = $\left(\frac{y}{x}\right)$

So if you graph Mass = y and Volume = x

The Slope is the average Density

This is a great way of determining Density.

A fun experiment is to have students find the mass and volume of different numbers of pennies ( which vary in mass density) . Then graph the results to find an average density.
