Methane gas, CH4 (g) , reacts with oxygen(g) to produce carbon dioxide gas and water vapor according to the equation: C2H4(g) + 3 O2(g) → 2 CO2(g) + 2 H2O(g)
(a) How many milliliters of ethene gas, C2H4 (g) and excess oxygen gas are needed to produce 55.5 L of carbon dioxide gas at STP ?
(b) Suppose the density of ethene gas is 0.0155 g/cm3, how many grams of ethene are needed under these conditions?
