A series of practice problems related to the concept of density. It covers various scenarios involving different materials such as iron, aluminum, oil, and metals, where the density, mass, and volume are given, and the goal is to calculate the missing parameter. The problems range in difficulty and provide step-by-step solutions, allowing the reader to understand the application of the density formula and the relationship between the three fundamental properties. This document could be useful for students studying physics, chemistry, or materials science, as it reinforces the understanding of density and its practical applications. The problems cover a wide range of topics, including the comparison of volumes and masses of different materials, the determination of the density of unknown substances, and the evaluation of the suitability of containers for specific liquids based on their densities.

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 31.6 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 27.0 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 2.7 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.
No, 152 mL > 100 mL. Would a 100 mL graduatedcylinder hold 250 g of mercury (density = 13.6 g/cm3)? - answer ✅✅1 mL = 1 cm Volume = 18.3823529412 mL rounded->18 mL 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, 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.
