A mixture solution of Na2S, NaOH and Na2CO3 was analyzed in a lab and the results shows that it contains 20 g Na2S /L, 160 g NaOH /L, and 100 g Na2CO/L. If the solution's specific gravity is 1.03, calculate the following (and follow the same order a) to e) while solving): a. Mass fractions of Na2s, NaOH, Na2CO3 and H2O. b. Average molecular weight. c. ppmw of Na,s

Question
A mixture solution of Na2S, NaOH and Na2CO3 was analyzed in a lab and the results shows that it contains 20 g Na2S /L,160 g NaOH /L, and 100 g Na2CO3/L. If the solution's specific gravity is 1.03, calculate the following (and follow the same order a) to e) while solving): a. Mass fractions of Na2S, NaOH, Na2CO3 and H20. b. Average molecular weight. c. ppmw of Na2s d. mass flow rate of Na2S (Ibm/min) corresponding to a total stream flow of 700 kgmol/h. e. Do you think changing the concentrations of Na,S, NaOH and Na,CO3 will affect the density of the above mixture? Why?
