2. A solid block with a length of 6.0 cm, a width of 3.0 cm, and a height of 3.0 cm has a mass of 146 g. What is the block's density? Show all work.

3. To determine the density of an irregularly shaped object, a student immersed the object in 21.2 mL of water in a graduated cylinder causing the level of the water to rise to 27.8 mL. If the object has a mass of 22.4 grams, what is the density of the object?

Kolten Coleman · Answer 1

2: Volume V = a*b*c = 6.0*3.0*3.0 = 54.0 cm^3 density ρ = mass/volume = 146/54 = 2.70 g/cm^3

3: Volume = (27.8 - 21.2) cm^3

mass = 22.4 g

density = 22.4 / (27.8-21.2) g/cm^3
