This document discusses density and how to calculate it by dividing mass by volume. It provides the formula, D = m/v, and examples of calculating density when given the mass and volume of different objects, or using density and one value to find the other. Density can be used to determine if an object will float or sink in water based on its density compared to the density of water.

DensityMeasures how much matter (mass) is in a certain amount of space (volume)
Calculating DensityDensity equals mass divided by volumeD = m / vg/mL or g/cm3
Sample Problem #1What is the density of a chocolate bar that has a mass of 55.6 g and a volume of 30 cm3 ?
Sample #2What is the mass of a gold brick that has a density of 19.3 g/mL and a volume of 15 mL?
Sample #3What is the volume of silver that has a density of 10.5 g/cm3 and a mass of 25 g
Applying DensityWhy do some objects float in water while others sink?
