Nitrogen gas is collected over water in a eudiometer. The volume of the nitrogen gas is 45.5 mL, the atmospheric pressure is 756.0 mm Hg, the water temperature is 24.0C, and the water level inside the eudiometer is the same as the level of water in the beaker.

(a) Calculate the pressure of the dry nitrogen gas. Bax your answer
(b) Calculate the volume of the nitrogen gas at STP.

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.
