  1. MOLECULAR FORMULA • whole number multiple of the empirical formula • need: empirical formula MM of molecular formula

  2. MOLECULAR FORMULA What is the empirical formula of a cmpd that 27.3% C and 72.7% O?

  3. MOLECULAR FORMULA The molecule’s MM is 132.03 g/mol. Calc. the molecular formula: 1. Find MM of the empir. formula.

  4. MOLECULAR FORMULA The molecule’s MM is 132.03 g/mol. Calc. the molecular formula: 2. Divide molecular MM by empirical MM.

  5. MOLECULAR FORMULA The molecule’s MM is 132.03 g/mol. Calc. the molecular formula: 3. Multiply all elements by the whole # to get the molec. formula.

  6. MOLECULAR FORMULA Calculate molecular formulas: Molar Mass Empirical Formula Molecular Formula 60 g/mole CH4N C2H8N2 181.5 g/mol C2HCl C6H3Cl3
