MOLECULAR WEIGHT(MW)
WEIGHT OF ONE ATOM / ATOMIC WEIGHT
PERCENTAGE OF ONE ATOM(P)
EMPIRICAL FORMULA(EF)
MOLECULAR FORMULA (MF)
EMPIRICAL FORMULA WEIGHT(EFW)
FORMULA
MW= ADD ALL ATOMIC WEIGHT
P = ATOMIC WEIGHT/MW X 100
MF = COMPOUND STRUCTURE
REDUCED MF = EF
ATOMIC WEIGHT OF ALL THE EF ATOMS = EFW
CH3COOH - MOLECULAR FORMULA
EMPIRICAL FORMULA = CH2O
N= MOLECULAR WEIGHT / EF WEIGHT
CH3COOH -12+3+12+16+16+1 =60
CH2O-12+2+16=30
N=60/30=2
