[Answer: C]
molecular mass of ozone is 48g/mol
oxygen: 16g/mol per oxygen
48/16= 3

The formula of ozone is 03 meaning there are three oxgen atoms in a molecule. Atomic mass of oxygen is 16, so molar (molecular) mass of ozone is 3 x O = 3 x 16 = 48 therefore the reverse give you your answer. 48/16 = .....3!

Looks to me like you want somebody to do your chemistry homework for you. Looks like its working.
Kudos to you. Too bad Yahoo answers can't help you through the test as well.
