Department of Chemical & Biochemical Engineering Rutgers, The State University of New Jersey 98 Brett Road Piscataway, NJ 08854 14:155:201 Chemical Engineering Analysis I Homework Assignment 1 (due 9/11/08) 1. At 25°C, an aqueous solution containing 35.0 wt% H 2 SO 4 has a specific gravity of 1.2563. A quantity of the 35% solution is needed that contains 195.5 kg of H 2 SO 4 . (a) Calculate the required volume (L) of the solution using the given specific gravity. (b) Estimate the percentage error that would have resulted if pure-component specific gravities of H 2 SO 4 (SG=1.8255) and water had been used for the calculation rather than the given specific gravity of the mixture. 2. Liquid toluene is flowing through a pipe at a rate of 175 m 3 /h. (a) What is the mass flow rate of this stream in kg/min? (b) What is the molar flow rate in mol/s? (c) In fact, the answer to part (a) is only an approximation that is almost certain to be slightly in error. What did you have to assume to obtain the answer?
