A flask half-filled with methanol is left un-stoppered. The liquid methanol equilibrates with the methanol vapour in the air inside the flask. Atmospheric pressure in the room is 1 bar. The partial pressure of methanol in the vapour in the flask, at 293 K, is 0.13 bar Calculate the mole fraction of methanol in the vapour above a mixture containing 1 mole of ethanol mixed with 2 moles of methanol, at 293 K, at a pressure of 1 bar, using the value of the 0.13 bar for the vapour pressure of pure methanol at this temperature.

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. the only problem is that you do not know what element will form. by your previous calculations you know that you will have 6.3 moles of product. when it is complete, you weigh it and determine you have 604.4 grams. what element have you produced?
