what is stoichiometric calculation?
Asked by | 23rd Jun, 2008, 12:56: PM
Once the reaction equation is balanced we usually want to use it to calculate amount of reagents that take place in the reaction. Sometimes we want it to be able to evaluate stoichiometric amount of reagents needed for some chemical process, sometimes we want to use it for the calculation of the titration (determination) result - regardless of the reason, we have to perform a stoichiometric calculation.
While the stoichiometric information in the reaction equation is based on moles, it can be easily converted to masses - with the use of molar masses.
There are two basic methods of performing stoichiometric calculations - one is based on ratios and proportions of reagents, and the second on so-called dimensional analysis (which is not the best name, as dimensional analysis is also a much more complicated and advanced method, used for completely different purposes).
