To find the theoretical yield of oxygen in potassium chlorate (KClO3) by weight, we need to calculate the molar mass of KClO3 and then determine the mass of oxygen in it.The molar mass of KClO3 is calculated as follows:- Potassium (K): 39.10 g/mol- Chlorine (Cl): 35.45 g/mol- Oxygen (O): 16.00 g/molSo, the molar mass of KClO3 is:39.10 + 35.45 + (3 × 16.00) = 122.55 g/molThe mass of oxygen in KClO3 is:3 × 16.00 = 48.00 gTherefore, the theoretical yield of oxygen in KClO3 by weight is 48.00 grams.
