You need to calculate the molecular weight of KClO3 (let's say 122.55 g/mol, depending how you treat isotopes), so 1.25 kg of potassium contains 12500/122.55 ~ 102 mols, and these give 102/2x3 = 153 mols of O2

At STP 1 mol of an ideal gas occupies a volume of 22.4 l, so the result is around 3427 l.

Did I remember this correctly? It's been over 10 years ago.

Dimensional analysis nigger

mass of KClO3 / mass of one mole of KClO3 * [ 3 O2 moles / 2 KClO3 moles ] * 22.4 L/mol of gas
