CH 3: Stoichiometry Moles. Mole Defined Mole = number equal to the # of carbon atoms in exactly 12 grams of pure C-12. –Mole = 6.022 x 10 23 –Called Avogadro’s.
Stoichiometry Mole Ratios Mole Ratios Limiting Reagent Limiting Reagent % Yield % Yield Gas Stoichiometry Gas Stoichiometry.
MOLAR HEAT: it is the enthalpy changes(ΔH) for 1 mole of substance to change a state. Molar Heat of Fusion (ΔH fus ): the amount of heat absorbed.
CHAPTER 3. STOICHIOMETRY Determination of quantities of materials consumed and produced in a chemical reaction.
