DensityNotes

Density= mass

volume

Density's units are grams/liters 'or'' grams/centimeters cubed

Formula for determining Density:

1. write out the formula (Density= mass/volume)
2. determine which part is missing (i.e. either the mass, volume, or density is what you are trying to determine)
3. plug the numbers you are given into the formula
4. multipy or divide to determine the answer
5. check to make sure you have the right answer in the right units!

Example

Question: A piece of lead has a mass of 22.7 grams and occupies a volume of 2.00 liters. What is the density of the lead?

Solution:

1. Write out the formula

Density=mass

volume

1. Plug in the numbers

X=22.7 grams

2.oo liters

1. Now solve for X:
