What is percent yield formula?
Actual yield\ Theoretical yield x 100
What is the limiting reactant
The reactant that is completly used up in an equation
What is the excess reactant
The reactant that is left over in a reaction
What does the law of conservation of mass state?
Matter is neither created nor destroyed in a reaction, meaning the mass of the reactants ALWAYS matches the product.
How do you convert moles to grams in a balanced stoichiometry problem?
