The Steps of Stoichiometry

Stoichiometry is a six step system that requires converting moles to grams. For step one you must write a balanced equation for the reaction an example would be 6 CO2 + 6 H2O → C6H12O6 + 6 O2 this is the balanced equation for photosynthesis. For reactants to be equal, their must be the same amount on each side, meaning if their is six on one side then their has to be six on the other side so that the chemical is balanced. After balancing the equation you then must write a given mass on a factor label form, to find the given you must multiply mass by mass. After finding the mass in grams the next process is to convert the reactants mass into moles, to do so the sums of the atomic weight of each element are multiplied by the molar mass constant.

After finding the mole, you must then convert the moles of reactant to moles of product. To find moles of product you have to find the molar relationship by finding it from the corresponding balanced equation. Once again the next step is conversion but this time grams to products, to do this you must use a compounds molar mass and multiply by grams to get your product. All units have now been solved the last step is to pick up a calculator and do the math.
