'''''Density''''' is a measure of the quantity of mass of a substance that occupies one unit of volume. ;;Density= <u>mass</u>:volume Density's units are grams/liters '''''or''''' grams/centimeters cubed ''Formula'' for determining Density: #write out the formula (Density= mass/volume) #determine which part is missing (i.e. either the mass, volume, or density is what you are trying to determine) #plug the numbers you are given into the formula #multipy or divide to determine the answer #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:'' #Write out the formula ;;Density=<u>mass</u>:volume #Plug in the numbers ;;X=<u>22.7 grams</u>:2.oo liters #Now solve for X: X=11.4 grams/liters
