Consider the following reaction.
2KClO3(s) ¨ 2KCl(s) + 3O2(g)
A)How many grams of KCl are produced from the complete reaction of 10.9 mol of KClO3?
B)How many grams of KCl are produced from the complete reaction of 86.2 g of KClO3?
The balanced reaction indicates you will get 10.9moles of potassium chloride (mole ratio 2:2). So how many grams of KCl is that?
massKCl=moleKCl*formula mass KCl
b. figure first the moles of potassium chlorate in 86.2 g (
then, proceed as in a
