How does the best fit line of mass and volume relate to density

[From: ] [author: ] [Date: 12-11-01] [Hit: ]
If you were to plot mass against volume,As there are errors in both the meausrement of mass and volume, mearuing density is subject to these errors twice over (i.e. in both mass and density).One way to overcome some of the errors is to make measurement of both the mass and volume of various masses of a material.......
I also need a more clarifying definition of density.,

-
Density is the mass per unit volume, so how much 1 cubic metre of a substance would weigh.

density=m/V

If you were to plot mass against volume, the gradient of your line would be the density

-
Density is defined as mass per unit volume: d=m/v

As there are errors in both the meausrement of mass and volume, mearuing density is subject to these errors twice over (i.e. in both mass and density). One way to overcome some of the errors is to make measurement of both the mass and volume of various masses of a material. Then, calculate the line of best fit of volume to mass. The slope of the line is the slope of the line is the density. The zero offset is the equipment zero error.
