a. calculate the mass flowrate of solvent C in stream 4.

b. Calculate the composition of stream 6.

please no answer from chatgpt or other ai, it will obviously be wrong since you cant feed it the data from the flowchart

3. In a liquid-liquid extraction process, solvent C is used to extract solute B from a mixture of solvent A and solute B. In each stage of the 2-stage extraction process, 90.0% of the solute B that enters in the solvent A and solute B feed stream is extracted and leaves in the Solvent C outlet stream. The 2 solvents are immiscible, meaning they do not mix together. Use this space to write your balances and equations: mB2=0.1mB1
