A test tube containing a mixture of KCl, KClO3, and MnO2 having a total weight of 23.584 g was heated to compose the KClO3. After heating, the mass was found to be 22.347 g.
a)How many moles of oxygen gas were evolved?
b)Calculate the number of moles and the mass of KClO3 originally present in the test tube.
c)If the original mass of the sample were 4.39 g, calculate tbe percent KClO3 in the original sample.
