Explanation:
The chemical reaction taking place is expressed as;
#Calculate the moles of calcium chlorate in the reaction given a molar mass of
:
#The ratio of calcium chlorate to oxygen produced is 1:3.
#The molar mass of oxygen is given as 32. We therefore calculate the mass produced as:
Hence, the mass of oxygen produced is 115.95 g
