Question

graphical method of determining density
scatter plot of (y - axis) versus (x - axis)
based on your graph, what is the density of the aluminum foil?
6 g ml⁻¹

Explanation:

Step1: Recall density formula

Density $
ho=\frac{m}{V}$, and in a mass - volume graph, the slope of the line represents density.

Step2: Identify slope from equation

The equation of the line is $y = - 0.187936x+0.172278$. The slope of the line is - 0.187936. But density cannot be negative in this context, likely due to an incorrect data - fitting or axis - labeling issue. Ignoring the sign, the magnitude of the slope gives the density.

Answer:

$0.187936\ g/mL$
