Molar Mass

MOLAR MASS is the mass in grams of 1 mole of a substance

• unit= g/mol
• Gram Molecular Mass

1. Covalent Compounds (no metals)

• Gram Formula Mass

1. Ionic Compounds

JUMPING RIGHT IN...

• C3 H8 

C 3 (# in compound)  x 12.01 (Periodic Table) = 36.03

H 8  (# in compound) x 1.01 (Periodic Table) = 8.08

36.03 + 8.08 = 44.11 g/mol 

DIATOMIC ATOMS

H2,       O2,      F2,    Br2,     I2,     N2,      Cl2 

they only double their mass when ALONE

EX: O2 --> (2)(16.00)= 32.00 g/mol
