Question

15.0g of potassium trioxochlorate(v) was crushed and heated with about 0.1g of manganese(iv)oxide, calculate the mass of chloride that would be produced assuming the reaction was complete
For whatever it's worth, the correct IUPAC name for KClO3 is potassium chlorate.
..................2KClO3 ==> 2KCl + 3O2
mols KClO3 = g/molar mass = 15.0/122.5 = 0.122
2 mols KClO3 will produce 2 mols KCl; therefore, 0.122 mols KClO3 will produce 0.122 mols KCl. Convert to g. gKCl = mols KCl x molar mass KCl = ?
