- 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.When a pure sample of tert-butyl bromide is analyzed by gas chromatography, two components are usually observed.

- What may be the complications in doing nitrous acid test and how will it be resolved?Each of the student statements below is wrong. Explain why they are not correct. (a) All my compound dissolved right away in the small amount of solvent I added at room temperature, and I didn’t need to heat it at all. This means I’m going to get lots of pure compound out. (b) I did a recrystallization of naphthalene and my percent recovery was very high (99%), so I must have pure product. (c) When you’ve dissolved all your compound in hot solvent, and you’re in a hurry, it’s ok to just place it straight into the ice bath..What volume of 1.37 M nitric acid is needed to convert 9.0 g of m-bromophenol to 3-bromo-4,6-dinitrophenol?
