You need to prepare blood for a transfusion. You have the following three processed blood packs available:
Pack A – Enriched in red blood cells (RBCs)
Contents: 2.5 wt% white blood cells (WBCs); 50.0 wt% isotonic fluid; the rest is RBCs.
Pack B – Enriched in serum proteins
Contents: 50.0 wt% serum proteins; 1.0 wt% WBCs; 18.0 wt% isotonic fluid; the rest is RBCs
Pack C – Isotonic fluid
Contents: 100.0 wt% isotonic fluid
All three packs must be mixed in the correct proportions to generate blood for a transfusion pack. The transfusion pack needs to have the following composition: 2.0 wt% WBCs and 12.6 wt% serum proteins.
a. Write out mass conservation equations for RBCs, WBCs, isotonic fluid, serum proteins, and total mass.
b. Calculate the weight percent (wt%) of RBCs and isotonic fluid in the transfusion pack.
c. What is the ratio of the mass of pure isotonic fluid (Pack C) to the mass of Pack A?
d. What is the ratio of the mass of Pack B to the mass of Pack A?
