Calculate the mass of water produced. Show your work. [H = 1.008, O = 16.00]

Question

- When ethene, C2H4 (g), is completely combusted, carbon dioxide, CO2(g), and water vapor, H2O(g), are produced according to the following balanced equation: 

C2H4 (g) + 3 O2 (g) → 2 CO2 (g) + 2 H2O (g)

If 11.2 L of carbon dioxide gas is produced at STP, answer questions a – c.

(Assume that all volume measurements are made at the same temperature and pressure)
