Calculating Density Practice Worksheet #3



Calculate the density and identify substances using a density chart.SubstanceDensity (g/cm3)Gold19.3Mercury13.5Lead11.4Iron7.87Aluminum3.7Bone1.7-2.0Gasoline0.66-0.69Air (dry)0.00119Density is a measure of the amount of mass in a certain volume. This physical property is often used to identify and classify substances. It is usually expressed in grams per cubic centimeters (g/cm3) or grams per milliliter (g/mL). The chart to the right lists the densities of some common materials.Use the information and solve each problem. Every box must be filled in for credit.Problem StatementFormulaDefine VariablesSubstitutionAnswerExample: What is the density of a billiard ball that has a volume of 100 cm3 and a mass of 250 g?D = m/vm = 250 gv = 100 cm3D = 250 g 100 cm32.5 g/cm31.A small cookie has a volume of 3200 cm3 and a mass of 523 g. What is the density of the cookie?2.A block of wood has a density of 0.6 g/cm3 and volume of 2.6 cm3. What is the mass of the wood?3.A .9 kg boulder has a density of 8 g/cm3.
