Stoichiometry Made Simple!

Learn stoichiometry with every step shown: balancing equations, calculating molar masses, converting grams to moles, using mole ratios, and converting back to grams. Follow a complete nitrogen-to-ammonia example, with every conversion factor explained and units canceled on screen. Then try an aluminum oxide problem yourself, pausing at each step before checking the solution. In this lesson: • Coefficients versus subscripts • Why reaction ratios compare moles, not grams • Calculating molar mass • Setting up conversion factors and canceling units • Significant figures and rounding • Checking theoretical yields with estimates and conservation of mass Bring a calculator, periodic table, and paper, and work along at your own pace. Both examples assume complete reaction of the stated reactant, with the other reactant in excess.
