Answer 2

he answer is B, 20.6g of O2 produced.

first you need to convert the mass of LiClO3 to moles by using the equation n=m/M. You then need to multiply this number in ratio to how much oxygen is produced, a ratio of 2:3. then you need to convert this number of moles of oxygen to mass by using the equation n*M=m.
