Stoichiometry calculator: limiting reagent and yield

Balance the reaction, enter reactant masses and calculate the limiting reagent, theoretical product and percent yield.

Enter an equation, then reactant masses such as H2=4; O2=40. Choose the target product and optionally enter the actual product mass in grams.
