A 15 L sample of a gas is at STP. What is the # of mole of this gas? R= .0821latm/K mol

Which best describes how johannes kepler developed his laws of planetary motion

If an area has high air pressure and low humidity, what type of weather will it most likely have? plz !

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.
