OH CH₂OH OH CH₂OH OH + H+ OH OH OH NH2 NH pKa = 9.0 A scientist claims that at pH=7.0, a solution of this compound would contain about 90% of the species in the charged form (-NH3+) and about 10% of the species in the uncharged form (-NH2). Is this scientist correct? If not, provide the correct percent- ages for these two species in the solution.

The enzyme urease is widely used for determining urea concentration in blood. The Michaelis constant for urease at room temperature is 2.0 mM and k2 = 2.8 × 104 s-1 at pH = 7.5. Based on the kinetic experiment, when 0.34 mM urease was used, the initial rate of the reaction was determined to be 3.49 M/sec. What is the concentration of urea in blood in unit of mM? Please keep your answer to two decimal place. Please convert all concentration unit to mM in calculation.
