In the molecular weight determination by the Dumas method, several grams of an organic liquid was drawn into a bulb. The bulb was then immersed in a water bath at 87 degrees C and kept there until all the liquid was vaporized and the air in the bulb was replaced by the vapor. The tip was then sealed shut and the bulb removed from the vapor was 36.127g; the weight of the empty (evacuated) bulb was 35.427g; the bulb’s volume was 200.0mL; room temperature was 25 degrees C, and the barometric pressure was 720 mm Hg. Calculate the molecular weight of the organic liquid. Calculate the molecular weight of the organic liquid.
