i need help eoth this question

Two separation units are arranged in series (one after another) are fed a 100 kg/hr of a mixture of 50 wt% A, 50 wt% B, as shown below. The product stream from the first separator (Stream #1) is fed an additional 20 kg/hr of the same feed mixture, and that new solution (Stream #2) is fed into the second separator for additional purification. Using the figure below, provide the overall mass flow rates and species mass fractions for the streams labeled #1, #2, and #3. 20 kg/hr XA = 0.5 100 kg/h #1 #2 2 #3 *A=0.5 70 kg/hr 10 kg/hr X8 -0.7 X8-09
