Hello, I wanna know how to calculate stoichiometric ratios for reactions. I know that stoichiometric ratios are basically balanced out reactions converted into percentages. I know how to balance out chemical equations, and I know that there has to be an equal amount of moles for each reactant for a stoichiometric ratio. How do I convert "that" into percentage though? I can't seem to find any proper tutorials on that

I do not understand your question. Can you clarify what you mean by percentages?

Yeah I kinda did make it confusing back there, sorry. It's just that I wanna learn how to calculate the stoichiometric ratio for kno3 + sugar. The equation is 2 KNO3(s) + CH2O(s) → 2 KNO2(s) + CO2(g) + H2O(g). Knowing this, I wanna know how much of kno3 and sugar to add in percentage. And I dunno how to do that. Example 65% kno3 and 35% sugar.

if you know molar ratio converting it to mass ratio (hint: molar mass) is trivial. Mass ratio can be always expressed as percentage (hint: if you mix 10g of this with 30g of that, mass percentage of this is 10/(10+30)×100%, just apply the definition).
Note: sugar/nitrate mixture borders pyrotechnics, we don't discuss pyrotechnics at the forum.

Oh? Thanks so much for the info, idk I don't view it as something as serious as pyrotechnics, just a basic experiment for fun
