2KClO3 ==> 2KCl + 3O2
Use PV = nRT and calculate n for Oxygen.
Using the coefficients in the balanced equation, convert mols O2 to mols KClO3.
Now convert mols KClO3 to grams. g = mols x molar mass = ?
One way to generate oxygen is to heat potassium chlorate, KCLO3 (the other product is potassium chloride). If 386 mL of oxygen at 41 degree centigrade and 97.8 kPa is generated by this reaction, what is the minimum mass of KCLO3 used?
