Help!! Can someone please show me how to set up this problem. I'm lost. C3H8+5O2-->3CO2+4H20 If 19.2g of C3H8 and 19.2g O2 react, how many moles of CO2 can be produced?

So I have the balanced equation: c3H8 +502 = 3C02 +4H20 Question: At STP propane (C3H8) burns in oxygen to form 2.15L of carbon dioxide and water. So I've got 2.15 L x 1 mole /22.4 L But when I try to do the mole ratio, I don't know what to do since the 2.15 L is of carbon ...

Many portable gas heaters and grills use propane, C3H8(g). Using enthalpies of formation, calculate the quantity of heat produced when 15.0g of propane is completely combusted in air under standard conditions. Assume that liquid water is forming.

Balance each of the following skeleton equations. C) C3H8 + O2 -> CO2 + H2O This one was a bit harder for me to balance out, but this is what I managed to do. C3H8 + O2 -> 3CO2 + 8H
