As this seems to be a homework question and especially because you have already gotten people to help you cheat on your homework, I am not going to give you the answer. I will, however, tell you how to get the answer. First you need to get out a Periodic Table and figure out the molar mass of CH4 by determining the sum of the masses of one atom of carbon and four atoms of hydrogen. Then you divide the mass of the methane that you have by the molar mass of methane to find out how many moles you have. Now you need to balance the chemical equation for the reaction. Dezimae has already told you how to do this (http://www.answerbag.com/a_view/6352469). From this you get the ratio of methane molecules burned to water molecules produced. You use this ratio to determine the number of mols of water molecules you will have.
