I'm supposed to find how many grams of potassium nitrate is required to produce 536g of potassium nitrate, according to the equation: 2KNO3(s) --- 2KNO2(s) + O2(g) I calculated and balanced the equation and got: 2 KNO3(S) = 2 KNO2(S) + O2(g) Now I'm not sure what to do from here.

The equation looks balanced. :) But is the question supposed to be looking for grams of potassium nitrate required to produce 536g of potassium nitrITE?

@JoannaBlackwelder Yes, I've already balanced the equation as you can see, but I don't know what to do next.

Potassium nitrate reacts in a 1 : 1 mole ratio to produce potassium nitrite.

First find the number of moles of potassium nitrate available.
