My school is very correct
The equation is balanced already
2KCLO3 - 2KCl +3O2
Then
2 moles of KCLO3 produces 3 moles of O2
2 moles of KCLO3 produces =X
:::2*3/2 =3
it produces 3 miles of 02
Number of moles = volume /volume at stp
Then volume of oxygen = 3 moles * 22.4dm3
=67.2dm3

They are very correct, the only error I depicted is the use of 3CO2 instead of 3O2

wRONG!

IT MEANT2B 2MOLE OF KCLO3 WILL YIELD 3MOLE OF OXYGEN

SO 22.4dm3 at stp will yield X

HENCE 2 * 3

22.4 X

ans is meant2b33.6dm3
