A drug having a molar mass of 160 is being produced in a reactor.  The aqueous effluent (exit stream) of the reactor is flowing at the rate of 8 L/min, has a specific gravity of 1.051 and has a drug concentration of 42.9 wt%. If we take a basis of 100 kg of the reactor effluent stream determine the:  d)concentration of drug in grams per L e) mass flow rate of drug out of the reactor in grams/min f) molar flow rate of drug out of the reactor in mols/min

Question

A drug having a molar mass of 160 is being produced in a reactor.  The aqueous effluent (exit stream) of the reactor is flowing at the rate of 8 L/min, has a specific gravity of 1.051 and has a drug concentration of 42.9 wt%. If we take a basis of 100 kg of the reactor effluent stream determine the: 

d)concentration of drug in grams per L

e) mass flow rate of drug out of the reactor in grams/min

f) molar flow rate of drug out of the reactor in mols/min

 

Expert Solution
Step 1

Basis: 100 kg solution of reactor effluent stream

First, calculating the density of the drug solution:

SGsolution = ρsolutionρwater 1.051 = ρsolution1000ρsolution = 1051 kg/m3
