a. There is a certain copper containing protein, abbreviated P, which contains two copper atoms per molecule of protein. The molar mass of P is 107,000g/mol. What is the mass % of copper in the protein?  b. The concentration of P in blood is 15.5g P/100 mL blood. What is its molar concentration?  c. P can bind O2(g). If the O2(g) pressure is 0.16 atm at 37 degrees Celcius, what is the molar concentration of the O2(g)?  d. The two copper atoms in P have the ability to bind one molecule of O2 (Cu-O-O-Cu). If at equilibrium, O2 is bonud to 60% of the R, what is the equilibrium constant for the reaction?  P+O2><RO2?  e. Hemoglobin, abbreviated Hb, is the oxygen carrier protein. The equilibrium constant for the reaction of Hb with O2(g) under the same conditions, Hb+O2><HbO2 is 225. What is the equilibrium constant for the reaction HbO2+P><RO2+Hb?   ANSWER ONLY A, D, E (NOT B AND C) note that the >< symbol means "equilibrium" symbol
