A plastic material weighs 2.68 pounds and has a volume of 3.5 L what is the density?

Answer 1

density = mass / volume

so the density will be 0.766 lb/L

if you need to convert this to standard units:

2.68 lb = 1.217kg

3.5L = 0.001 m3

so the density will equal 1.217 / 0.001 = 1217kg/m3

Answer 2

The density of the plastic material can be calculated by dividing its mass (2.68 pounds) by its volume (3.5 L). This gives a density of approximately 0.768 kg/L.
