A sample of carbon dioxide gas (CO2) at 3.0 atm is at 0 °C. This gas is compressed to 30 L, and pressure at this volume is measured as 4.0 atm. Assuming temperature remains constant, what was the initial volume of gas?

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.

Can you me with this i really appreciate it
