Atomic weight of H, S and O are 1, 32, 16 g/mol, respectively. a) Calculate the mass fraction of sulphuric acid in the product solution. b) Use 100 kg of Solution A as a basis, draw a flowchart of this process and perform the degree-of-freedom analysis. c) Calculate the volumetric feed ratio (i.e., litres of Solution A/litres of Solution B).

Yuno wants to assess the quality of water in the Clover Kingdom and the Heart Kingdom. In order to do this, he took a 200.0 ml sample (T= 20oC) from the two areas and titrated them with sodium thiosulfate. The water from the Clover Kingdom used up 7.15 ml of the titrant while 7.65 ml where used on the Heart Kingdom’s water. Prior to this, 0.1000g of potassium iodate (FM: 214.01 g/mol; 99.97% purity) was weighed and subsequently dissolved in 150.0 ml of distilled water. He took 20.00 ml aliquot of this solution and added 20.00 ml of distilled water. He then treated the solution with potassium iodide and sulfuric acid. Finally, Yuno titrated the solution with 13.7 ml sodium thiosulfate titrant. Calculate the DO content of the two samples. Express your answer in ppm O2. Reminder: Follow proper significant figure rules Clover Kingdom: ____ ppm O2 Heart Kingdom: ____ ppm O2
