  9. QOTD • What is a mole? • How is a mole used? • Which are coefficients and which are subscripts in the chemical formula 2 H2 + O2 2 H2O ? • What is stoichiometry?

  10. Molar Mass (Molecular Weight) • The units for molar mass are g/mol

  11. Molar Mass (Molecular Weight) • 1 mole H2O = • 1 mole NaCl = • 1 mole Pb(NO3)2 =
