A series of practice problems related to density calculations, along with their solutions. It covers various scenarios, including finding density given mass and volume, finding volume given mass and density, and finding mass given density and volume. The problems involve different materials like iron, aluminum, oil, and other metals, offering a comprehensive practice for students learning about density. It also includes comparative problems and real-world applications, such as determining if a graduated cylinder can hold a certain amount of liquid based on its density. Useful for students to test their understanding and application of density concepts.

Actual solution.
A sample of iron has a mass of 31.6 grams and a volume of 4.0 cm3. Find the density iron. - answer ✅✅31.6g/4.0cm3=7.9g/cm Iron has a density of 7.9 g/cm3. Find the volume occupied by 31. grams of iron. - answer ✅✅31.6g/(7.9g/cm3)=4.0cm Iron has a density of 7.9 g/cm3. Find the mass of a piece of iron with a volume of 4.0 cm3. - answer ✅✅7.9g/cm3*4.0cm3=31.6g
What is the density of a metal if 38.6 grams of the metal occupy a volume of 2.0 cm3? - answer ✅✅38.6g/2.0cm3=19.3g/cm A piece of aluminium has a volume of 10.0 cm3 and a mass of 27. grams. What is the density of aluminium? - answer ✅✅27.0g/10.0cm3=2.7g/cm A 40 cm3 sample of oil has a mass of 35 grams. What is the density of the oil? - answer ✅✅35g/40cm3=0.875g/cm A rectangular solid measures 8.0cm20.0cm10.0cm. It has a mass of 3,040 grams. What is the density in grams per cubic centimeter? - answer ✅✅8.0cm20.0cm10.0cm=1,600 cm 3,040g/1,600cm3=1.8g/cm The density of iron is 7.9 g/cm3, and the density of aliminium is 2. g/cm3. Compare the volume of blocks of iron and aluminium both of which have a mass of 50g. - answer ✅✅The volume of the block of iron would be less than the volume of a block of aluminium, as iron is more dense. The density of iron is 7.9 g/cm3, and the density of aliminium is 2. g/cm3. Compare the masses of blocks of iron and aluminium both of which have a volume of 5 cm3. - answer ✅✅The mass of a block of iron would be greater than the mass of a block of aluminium, as aluminium is less dense.
Yes, 18 mL < 100 mL. The density of gasoline is 6.9 g/cm3 and the density of turpentine is 8.70 g/cm3. Suppose you find a 5 L (5,000 mL) can that is full of one of these liquids. You do not know which, and the label has fallen off. How could you tell which one is in the can without removing the lid? - answer ✅✅You could fill a container with gasoline, and place the mystery can into the container. If the can sinks then the liquid is turpentine. If not, the liquid is gasoline.
