- 7. During week l's lab we investigated the effect of different soaking solutions on the behavior of red blood cells. If the blood had arrived on time, our prepper would have needed to know how to make up different concentrations of saline (NaCl) solution from a 2.7% stock solution of NaCl. Can you help her by filling in the table below? For each group of students, you want to make 9ml of either 0.9% saline or 0.45% saline.
