Topic 1.3

Homework check:

• Open the docs on Classroom
• Correct your hw in a different colour.
• Bring up your textbook and notebook when your name is called. 

Topic 1.3 - Learning Goals:

I can…

• Explain the concept of density and know which measurements are necessary to calculate the density of a substance 
• Calculate the density of a substance, in g/mL or g/cm3, using the density formula.
• Use density to determine the mass or volume of a substance by making a calculation
• Use density to identify an unknown substance, since density is a property of a substance 

Topic 1.3 - Key Words:

• Mass
• Density 
• Volume

1.3 - Density:

Density = a measure how much matter is packed into a given area. It is a property of a substance.

The closer the molecules are, the greater the density.

Density tells us how many grams of matter there are per a unit of volume.

1.3 - Density calculations:

Density = a measure how much matter is packed into a given area.

Common units:

grams per cubic centimeter (g/cm3) 

grams per milliliter (g/mL)
