a laboratory has a 3.0 mol sample of pure carbon and a 3.0 mol sample of pure helium. how many more grams of carbon do they have than grams of helium?
answer choices:
the carbon sample would have the same mass as the helium sample.
the carbon sample would have two times the mass of the helium sample.
the carbon sample would have three times the mass of the helium sample.
the carbon sample would have six times the mass of the helium sample.

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
