Density

Density

• Measures how much matter (mass) is in a certain amount of space (volume)

Calculating Density

• Density equals mass divided by volume– D = m / v– g/mL or g/cm3

Sample Problem #1

• What is the density of a chocolate bar that has a mass of 55.6 g and a volume of 30 cm3 ?

Sample #2

• What is the mass of a gold brick that has a density of 19.3 g/mL and a volume of 15 mL?

Sample #3

• What is the volume of silver that has a density of 10.5 g/cm3 and a mass of 25 g

Applying Density

• Why do some objects float in water while others sink?
