Use the specific heat capacity that you calculated for granite (.79j/g) to determine how many grams of granite at the initial temperature of 75 degrees Celsius must mix with 2,000g of water at the initial temperature of 20 degrees Celsius to result in a final system temperature of 20.45 degrees Celsius. Start by calculating how much heat energy is needed to change the waters temperature by .45 degrees Celsius.

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.
