Density Practice Problems

The density of the purple solid (larger solid) is 9.6 g/cm³. Predict whether the density of the pink solid (smaller solid) is lower than, higher than, or the same as the purple solid.

What is the volume (milliliters) of olive oil that weighs 2.5 kg? The density of olive oil is 0.92 g/mL.

The three solids below each weigh 50.0 g. Their possible identities could be zinc (d = 7.14 g/mL), platinum (d = 21.45 g/mL), or palladium (d = 12.03 g/mL). Determine the identity of each solid.

A block of metal has a mass of 173 g and a volume of 19.4 cm³. What is the identity of the metal?

Determine the density (g/mL) of a sample of lead with a volume of 24.1 cm³ and weighing 0.128 kg.

Calculate the density of a small ceramic figurine that weighs 443 g and has a volume of 128 cm³.

Determine the density (g/mL) of a sample of honey in the following scenario. An empty beaker has a mass of 104.256 g. The mass of the beaker increased to 303.130 g when 0.25 pt of honey was added to the beaker.

What is the density of a 0.60 lb block of cheese with a volume of 286.48 mL? Report your answer in g/mL.

Calculate the density (in g/mL) of a solution that has a volume of 40.0 mL and a mass of 42.8 g.

Mercury thermometers are being phased out of use due to the toxicity and relatively high melting point of mercury. An alternative is an alcohol thermometer, which is less toxic and can be used in lower temperatures. Alcohol thermometers usually contain pure ethanol, toluene, or isoamyl acetate containing a red dye. The densities of toluene and ethanol are 0.862 g/mL and 0.789 g/mL, respectively. If a thermometer can contain 3.0 mL of liquid, calculate the mass of i) toluene and ii) ethanol that can be placed in the thermometer.

Arrange the following from smallest to largest assuming that each cube has the same mass.

Silver cube (10.49 g/cm³)

Iron cube (7.874 g/cm³)

Copper cube (8.96 g/cm³)

Determine if a tennis ball with a diameter of 6.53 cm and mass of 59.4 g will float or sink in water?

Calculate the mass of 3.0 L of diethyl ether (density = 0.706 g/mL).

Calculate the volume for 1.45 kg ammonium nitrate. (density of ammonium nitrate = 1.72 g/mL)

Calculate the density of an unknown substance if a container can hold 300 g of water (density =  1.00 g/cm³) but only 75.22 g of the substance.
