A protein has a molar mass of 34400 g mol-1o-1-1o
a) Calculate the vapour pressure of this solution at 12.9o-3. An aqueous solution of this protein has an osmotic pressure of 0.712 kPa at 12.9C. The concentration of the protein (in g L) in this solution is 10.29g L. The vapour pressure of pure water at 12.9 C is 150.50pa.
C. You may assume that the solution is so dilute that its density is 1.00 g cm.
By using photons of specific wavelengths, chemists can dissociate gaseous H-I to produce H atoms with accurately known speeds. When H-I dissociates, the H atoms move away rapidly, whereas the relatively heavy I atoms move little. Average Bond Ener..
