Density is a quantitative property of matter that describes the amount of mass per unit volume a substance has
FORMULA: d = m/v Where, d=density m=mass
v=volume

What are the units for mass?mg, g, kg, lbs
When solving density problems the unit for mass typically used is grams or kilograms

What units are used for volume?
mL, L, kL, cm3, m3
Which units are used for solids and which are used for liquids?

What is the density of 5 g cube with one side having a length of 2 cm?
G: m=5g, v= 2x2x2 = 8 cm3
U: d=?E: d=m/vS: d= 5g/ 8 cm3
d= 0.625g/cm3
S: Therefore, the density of the cube is 0.63g/cm3

• What the density of a piece of wood that has a mass of 25.0 grams and a volume of 29.4 mL?
• Liquid water has a density of 1 g/mL. If a substance has a lower density than this, it will float. Will a plastic ball weighing 125 g with a volume of 250 cm3 float?

• Calculate the density of a liquid in a beaker.
• The beaker has a mass of 15 grams when empty. The beaker plus an unknown liquid has a mass of 34 grams. What is the density of the liquid if its volume is 10 mL?
• Calculate the mass for the following object.
• If you know that the object has a density of 17 g/ml and the volume is 5 ml.
