Question #203813

How many grams of potassium chloride are produced if 15 grams of potassium chlorate decomposes?"

Expert's answer

"2KClO_3\\rightarrow 2KCl+3O_2"

By this equation we say

potassium chlorate and potassium chloride

Are in 1:1 ratio

Moles of KClO_{3}="\\frac{given \\ mass}{molar \\ mass}=\\frac{15}{122.5}=0.12"

So mass of potassium chloride =0.12×74.5=8.94 g answer
