The mass of a glass bulb emptied of all its air is 36.194grams. When filled with 02 at 101kPa of pressure at 298K its mass is 36.406grams. When filled with a mixture of CH4 and C2H6 under the same conditions of temperature and pressure, its mass is 36.0333 grams. What is the percentage of moles of CH4 in the mixture?

I'm sorry, but I think your numbers must be off. If the empty bulb weighs 36.194g, it is impossible for the bulb filled with CH4 and C2H6 to weigh less than that, 36.0333g. If you would fix the numbers, I could surely help you out!
