3a. Calculate the required mass of an unknown nonelectrolyte (ℳ = 125.7998 g/mol) dissolved in 129.7 g of solvent that gives a solution that freezes at 1.85 °C. The freezing point of the pure solvent is 4.44 °C and its Kf value is 1.87 °C/m. Report your answer to TWO places past the decimal. 3b. Calculate the molar mass (in g/mol) of an unknown nonelectrolyte if 0.613 g dissolved in 250.3 mL of water at 19.47 °C has an osmotic...
Problen 1 1. For production of penicillin (CIGHsO4N S, molecular weight 334.4 g/mol), glucose CoHr2O) is used as substrate and phenylacetic acid (C H O2) is added as precursor. The stoichiometry for overall synthesis is: A supply of 100 mol/hr of glucose is fed to a continuous stirred-tank reactor for the production of penicillin, along with 200 mol/hr of ammonia (NHs),130 mol/hr of oxygen, 125 mol/hr of sulfuric acid and 100 mol/hr of phenylacetic acid. a. Determine the limiting reactant...
