CHBE 241 Material and Energy Balances Department of Chemical and Biological Engineering The University of British Columbia Assignment #2 Due: Thursday, 5 October 2006, 4:30pm CHBE Main Office 1. You go into the lab and put a 100-mL volumetric flask on a balance. You tare the balance so it reads 0 g. Then you measure anhydrous fructose (C 6 H 12 O 6 —the major sugar in fruit) into the flask until the balance reads 15.9 g. Then you fill the flask up to the 100-mL line with water. The balance now reads 105.97 g. Calculate the wt% fructose and mol% fructose of the solution. The molar mass of fructose is 180 g/mol and that of water is 18 g/mol. 2. Oxygen at 100 C and 75 psia flows through a pipe at 115 lb/min. Calculate the molar flow rate (lbmol/min), and the volumetric flow rate (m 3 /min) at both the actual temperature and pressure and at STP. 3. Curious Carl is very curious: He wants to know if nitrogen really follows the ideal gas law. To test this, he puts 1 mol N 2 into a rigid container with a volume of 22.414 L. Then Curious carefully changes the temperature of the container and measures the pressure. After repeating this at several different temperatures, he obtains these data: T(K) 100 200 300 400 500 600 700 800 900 1000 P(atm) 0.363 0.732
