What mass of ethane (ch3ch3) is contained in 50.0 ml of a 13.9% by mass solution of ethane in hexane?

the density of the solution is 0.611 g/ml.

How can you use chemical equations to predict the products of the reaction you can carry out?

Which element is the least metallic between cadmium, silver, zinc, or iron?

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.
