2KClO3 ==> 2KCl + 3O2
You must have made a typo. There is no c. You must have meant how much O2 is evolved.
mols KClO3 = grams/molar mass = 15/122.5 = 0.122
Convert to mols O2 produced. 0.122 mols KClO3 x (3 mols O2/2 mols KClO3) = 0.183
Convert to mass O2. grams O2 = mols O2 x molar mass O2 = ?
Post your work if you get stuck.
