11. If one hud is equivalent to 2.7 yeds, and 2.2 yeds is equivalent to one bof. How many huds equal 100 bofs? (Hint, start with 100 befs over 1 (You have 100 befs--this is the given), create conversion factors for the two
relationships given. Ex 1 hud = 2.7 yeds If one hud is equivalent to 2.7 yeds, and 2.2 yeds is equivalent to
one bof. How many huds equal 100 bofs?
Thud=27 veds.

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.
