How many grams of CO2 are formed by complete reaction with 33.7 of limestone?
If you’ve done any practice quesions or examples in class, go back and check these out. I don’t really know what grade you are in or what kind of chemistry training you’ve had, so I don’t want to give you an answer that is over your head, but you do need to use molar mass, which is the addition of atomic masses of all the elements in a molecule, mole ratios, and the formula n=m/M, where n is the number of moles, m is mass in grams, and M is the molar mass in grams. As for the volume, I was taught that 1 mole of gas at STP is 22.4 litres, which comes from the formula PV=nRT, where P is pressure (1atm at STP), V is volume in litres, n is the number of moles, R is the constant 0.08206 atmxmolxK, and T is temp in Kelvins (273 at STP).
