Which of the following shows the correct relationship among density, volume, and mass? 1. Density = volume/mass 2. Volume = density/mass 3. Mass = (density)/(volume) 4. Weight density = weight/volume
a. 1 and 3 c. 4
b. 1 and 4 d. 3 and 4
ANS: D
Given density, d = mass (m)/volume (v), the equation can be solved for each variable: m = dv, v = m/d. When mass is substituted by weight, dw = w/v.
