Measuring Volume and Mass Practice

What is the formula for mass, when density and volume are known?

• dV

• m/V

• m=dV

• V=m/d

A mysterious metal cube has a mass of 98.4 g and a volume of 12.3 cm³. Calculate the density of the cube and identify if it could be aluminum, iron, or lead.

• Aluminum

  Density: 2.7 g/cm³

• Iron

  Density: 7.9 g/cm³

• Lead

  Density: 11.3 g/cm³

While exploring a creek, a student discovers a strange mineral sample. In the lab, they find that the sample displaces 18.5 mL of water and has a mass of 46.3 g. Calculate the density of the mineral and determine if it could sink in water.

• 2.5 g/cm³

  It will sink.

• 2.5 g/cm³

  It will float.

• 0.4 g/cm³

  It will float.

• 0.4 g/cm³

  It will sink.

• 856.6 g/cm³

  It will sink.

A jeweler is crafting a pure gold bracelet. Gold has a density of 19.32 g/cm³. If the bracelet is designed with a volume of 8.75 cm³, what will its mass be? (do not include units)

A scientist is designing a device that requires a block of pure copper. Copper has a density of 8.96 g/cm³. If the block needs to have a volume of 275 cm³, what will its mass be? (do not include units)

A diver discovers a pure silver ingot while exploring a shipwreck. Silver has a density of 10.49 g/cm³. If the ingot has a mass of 524.5 g, what would its volume be? (do not include units)

An engineer is designing a protective shield using pure tungsten, which has a density of 19.25 g/mL. If the shield needs to weigh 500.0 g, what would its volume be? (do not include units)

A chef finds a mysterious kitchen tool and wants to identify its material. The tool has a mass of 15.8 grams and displaces 5.5 mL of water when submerged. Calculate the density of the tool and determine if it could be made of aluminum, stainless steel, or plastic.

• Aluminum

  Density: 2.7 g/mL

• Stainless steel

  Density: 8.0 g/mL

• Plastic

  Density: 1.2 g/mL

A jeweler places a gemstone in a graduated cylinder containing 50.0 mL of water. After submerging the gemstone, the water level rises to 65.3 mL. If the gemstone has a mass of 45.8 g, calculate its density. (do not include units)
