Question

The density of copper is 8.92 g/cm^3. If you plotted the mass of copper in grams versus the volume in cubic centimeters, what would the slope of the line be?

Answer 1

The slope would be 8.92g/cm^3.

D = m/V

m = DV

The equation for a straight line is

y = mx +b, where m is the slope and b is the y-intercept. We have

m = DV + 0

Thus, a plot of m vs V will give a straight line with a slope of D and a

y-intercept at the origin.

Slope = D = 8.92g/cm^3
