Density is the measure of how much mass is contained in a given unit volume. Based on the data for the four samples, determine which of the following substances has the lowest density.

• Sample 1: volume = 13 cm2 , mass = 30 g

• Sample 2: volume = 20 cm2, mass = 72 g

• Sample 3: volume = 2 cm2, mass = 22 g

• Sample 4: volume = 41 cm2, mass = 103 g
