A student measures the mass and volume of a small cube made of an unknown metal. The mass of the cube is 25.0 g, and the volume of the cube is 3.19 cm³. The student is told that the cube is a sample of one of the four metals listed in the table. Based on the data given, the unknown metal is most likely —

• Gold

• Iron
• Silver

• Tin

A balance and a graduated cylinder are used to determine the density of a mineral sample. The sample has a mass of 14.7 g and a volume of 2.2 cm3. What is the density of the mineral sample? 

• 0.15 g/cm3
• 32 g/cm3
• 13 g/cm3
• 6.7 g/cm3

Density is calculated by dividing the mass of a substance by its -

• volume
• weight
• length
• temperature

An object has a mass of 441 g and a volume of 10 cm3. What is the density of the object in g/cm3? .
