Aliquid stream consisting of 12.5 mol% n-butane and the balance a heavy nonvolatile hydrocarbon is fed to the top of a stripping column, where it is contacted with an upward-flowing stream of nitrogen. the residual liquid leaves the bottom of the column containing all of the heavy hydrocarbon, 5% of the butane entering the column, and a negligible amount of dissolved nitrogen. a) the highest possible butane mole fraction in the exiting gas would be that in equilibrium with the butane in the entering liquid (a condition that would require an infinitely tall column to achieve). using raoult�s law to relate the mole fractions of butane in the entering liquid and exiting gas, calculate the molar feed stream ratio (mol gas fed/mol liquid fed) corresponding to this limiting condition. b) suppose the actual mole fraction of butane in the exit gas is 80% of its theoretical maximum value and the percentage stripped (95%) is the same as part (a). calculate the ratio (mol gas fed/mol liquid fed) for this case. expert answer

what is your question? collegechemistry 5+3 pts in november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
