## anonymous one year ago How many moles of KClO3 reacted if 9 moles of O2 were produced in this reaction: 2KClO3 → 2KCl + 3O2

This will be done in a similar fashion, first try out yourself. I'll assist you through the process.

General Scheme for stoichiometric calculations: $$\sf \large 1.$$First write and balance an equation for the process described. $$\sf \large 2.$$Next, use the stoichiometric coefficients to find moles produced. $$\sf \large 3.$$ Set up a ratio using the species of interest, like so: e.g. for a general reaction: $$\sf \large \color{red}{a}A + \color{blue}{b}B \rightleftharpoons \color{green}{c}C$$ where upper case are the species (A,B,C), and lower case (a,b,c) are the coefficients , $$\sf \dfrac{n_A}{\color{red}{a}}=\dfrac{n_B}{\color{blue}{b}}=\dfrac{n_C}{\color{green}{c}}$$ From here you can isolate what you need. For example: if you have 2 moles of B, how many moles of C can you produce? solve algebraically: $$\sf\dfrac{2}{\color{blue}{b}}=\dfrac{n_C}{\color{green}{c}}\rightarrow n_C=\dfrac{2*\color{green}{c}}{\color{blue}{b}}$$ $$\sf \large 4.$$ Solve
