a) to identify the limiting reactant you grab your 2 items and you calculate how much u need. convert ur 1mol of CS2 to O2 in moles. The answer you get from that should be what you need. Then grab your O2 and convert it to CS2 using trigonometry. You have 1mol of O2 and your product is how much CS2 you need. to identify the limiting reactant you look for the element that is less then the amount you need.
b) grab your excesses element and subtract it from how much you need. your result will be your answer.
c) you just use trigonometry to figure it out
molA X molB/molA ( if you want to find grams then multiply by the molar mass)
