2KClO3 ==> 2KCl + 3O2
mols KClO3 = grams/molar mass = ?
mols O2 generated = mols KClO3 x 3/2 = ?
Use PV = nRT to solve for V in liters.
Post your work if you get stuck
calculate the volume of oxygen at 15°c and 745mmHg pressure which could be obtain by heating 10g of potassium trioxochloride.
(molar volume at stp is 22.4dm3. K = 39, Cl = 35.5 O = 10)

Why do you think the right method of approach should be the ideal gas equation? Don't you think the right method of approach should be a mix of mass-volume relationship with general gas equation?
