What is the density of a cell phone if its mass is 34.45g and has a volume of 90.25cm^3?

Answer 1

You need the relationship, Density = mass/Volume or D = m/V

Given: m = 34.45 g and V = 90.25 cm³ then D = 34.45 g / 90.25 cm³ = 0.3817 g/cm³

The mass value given is very low for a cell phone, so the answer is much lower than I would expect for a real cell phone. The density of a cell phone is >1 because it sinks in water, d = 1.00 g/cm³.
