Converting units
% m/v = 40 g/L = 40% m/v
ppm = mg/L
= 40 x 1000/L
= 40,000 ppm
M = 40 g/66,500 x L
= 0.0006 M

I need help with this ~
The osmotic pressures of mystery protein X are given below as a function of mass concentration c/(gL') 1.00 3.00 (kPa) 0.0200 0.120 Determine the molar mass of the protein in g/mol. Show any data transformations required below. Draw a graph which would enable you to determine the information required to solve this problem. You may use your graphing calculator to solve the problem but I still need to see the graph.

I need help finding the structure. For the formula I
got C8H9N but I'm not sure if this is correct. The part that I'm
struggling with is the proton NMR and finding each structure

Osmotic Pressure: You are trying to make artificial blood cells. You have managed to get pure lipids to form spherical bags (cells) of radius 10 μm, 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 a 1 mM salt solution prevents bursting, leaving the cell spherical and full of hemoglobin and water. Explain the reason why the cells burst...
