Activity 2 1-18-11 Molecular Masses

List the molecular masses of carbon dioxide, oxygen, and helium

Carbon dioxide + CO2
mass of O2 = 32
mass of C = 12
Mass of CO2 = 32 + 12 +44

Oxygen
mass of O2 = 32
mass of O=16
16 + 16 = 32

Helium
mass of He = 4

Water
H2O
mass of H = 1
mass of O = 16
2 + 16 =18
