1. The problem statement, all variables and given/known data t You are trying to make artifiial blood cells. You have managed to get pure lipid bilayers to form spherical bags of radius 10um, filled with hemoglobin. The first time you did this, you transferred the "cells" into pure water and they promptly burst, spilling the contents. Eventually you found that transferring them into 1 mM (one mili molarity) of salt solution prevents bursting, leaving the "cells" spherical and full of hemoglobin and water. a) If 1 mM is good, then would 2 mM be twice as good? What happens when you try this? b) Later you decide that you don't want salt outside because it makes your solution electrically conducting. How many moles per liter of glucose should you use instead? 2. Relevant equations p = cK(b)T c = n/V n = m/molar mass 3. The attempt at a solution So for A, since 1 mM made the solution isotonic, making the concentration of the solution higher would make the water from the cells go into the solution, shrivelling the cells. So if you increase to 2 mM, then it would not be a good idea. For B, I'm kind of confused. the Van't hoff relation formula is p(equil) = cK(b)T. This pressure is necessary for keeping the integrity of the cell. So when c = 1mM for the saline solution, it was able to achieve this integrity. p = 1mM*c*k(b)T So wouldn't this also work for glucose, keeping the concentration c =1 mM concentration making the pressure the same? I feel like I'm missing something.
