Answer:

KClO3 Decomposes to give KCl and O2

2KClO3 → 2KCl +3O2

Molecular weight of KClO3 is 39 +35.3+48 = 122.5 grams

Here 2 moles of KClO3 has taken, Hence molecular weight = 2X122.5 = 245 grams

According to the equation 245g of KClO3 Produces 3 moles of Oxygen

i.e 3X22.4 L = 67.2 L of oxygen is produced

At STP 1 mole equals 22.4 litres

245g of KClO3 → 67.2 L of oxygen

12.25 g of KClO3 → ? oxygen

= 12.25 X 67.2/245

=3.36 L

Volume of Oxygen released = 3.36 L required answer.
