(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Devise and preform an experiment to determine what fraction of the volume of a sample of Styrofoam is air. We know that Styrofoam is made of Polystyrene with air bubbles. The mass is the same, the volume is different.

2. Relevant equations

Mass/Volume=Density

3. The attempt at a solution

Well I thought that If I find the density of both the samples (Polystyrene and the Styrofoam) and find the difference and divide it by the density of the Polystyrene I could find the fraction of air, but I'm not very sure.
