This looks like a homework question. So, I am not going to give you the answer. However, I will tell you how to get it. First you need to get a Periodic Table of the Elements and look up the mass of each of the atoms in methane. Then you take these masses and multiply them by the number of each of the corresponding atoms in a methane molecule. Take the sum of the resulting masses. This is the mass of one mol of methane in grams. Divide the mass of the methane sample by this molar mass and you have the number of mols of methane. Balance the equation that tells you what you get out of this reaction. This will tell you how many mols of water you get for every mol of methane. Use this ratio to determine how many mols of water you will get from your sample of methane. Then you just need to turn back to your Periodic table to figure out the molar mass of water and then use this number to calculate how many grams this amount of water this is.
