Common mistakes to avoid in Stoichiometry. Incorrectly identifying the given (known) and wanted(unknown) quantities. Incorrectly choosing the limiting reagent. Using the coefficient when calculating the molar mass. Using the wrong units. Using the wrong conversion factor, example:
1mol or 1 mol
22.4 L 6.02 x 1023 particles
Practice solving the following problem:
How many moles of oxygen will be produced from 10 g of water?
