Question

The answer is given but I'd like to understand how one would get to the answer.

Answer 1

Find the limiting reactant.

Step-by-step explanation:

Using the ratio in the chemical formula, find the limiting reactant.

`0.164mol Mn*(2molMnO3)/(2molMn) = 0.164molMnO3`

`0.232molO2*(2molMnO3)/(3molO2) = 1.55molMnO3`

The second equation results in less mol of MnO₃, therefore it is the limiting reactant and changing the moles of O₂ to moles of MnO₃ which will give the theoretical yield which is 1.55 mol MnO₃.
