Ihave a special ideal balloon. this balloon does not exert any pressure on the gas inside it. i started by taking the balloon and inflating it to 4 l on brooklyn ny last night. the weather channel said that the temperature was 45.0 degree celsius, and the pressure was 50.27 mm of hg.
first i took this balloon scuba diving and went down to a depth of 100 ft where the pressure is 7 atm. and the temperature is 52.2 celsius. what is the volume of the balloon?

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.
