Question

How many grams of potassium nitrate (KNO3) are required to produce 536 g of potassium nitrite (KNO2) according to the equation below?
2KNO3(s) ---> 2KNO2(s) + O2(g)

Answer 1

turn that mass of potassium nitrite into \(moles\), and use the molar ratio from the balanced reaction.

you know that every time you \(make\) 2 moles of potassium nitrite, 2 moles of potassium nitrate must be \(used\) to make it
