1. 2.50g C2H4 x 1 mole C2H4 x 2 mol CO2 x 22.4 L at STP = 4.00 L at STP
Gaseous C2H4 reacts with O2 according to the following equation: C2H4(g) + 3O2(g) 2CO2(g) + 2H2O(g) What volume of carbon dioxide is theoretically produced from the reaction of 2.50 g C2H4?
2.50g C2H4 x 1 mole C2H4 x 2 mol CO2 x L at STP = L at STP
28.0 g C2H mol C2H mol CO2
