Part 1 Correct! A protein has a molar mass of 13700 g mol-An aqueous solution of this protein has an osmotic pressure of 2.13 kPa at 21.8 C. Calculate the concentration of the protein (in g L-1) in this solution. 1.19E1 g11 eTextbook and Media Hint Attempts: 2 of 3 used Part 2 Correct! Calculate the vapour pressure of pure water at 21.8 C. (The vapour pressure of pure water can be estimated from Pvap = 0.0074T3 -0.0234T2 + 6.2049T + 58.464, where I is in C and Pvap is in Pa.) 2.59E2 Pa.
