At high altitudes, mountain climbers are unable to absorb a sufficient amount of O2 into their bloodstreams to maintain a high activity level. At a pressure of 1.00 bar, blood is typically 95.0% saturated with O2, but near 0 feet where the pressure is 0.660 bar, the corresponding degree of saturation is 60.0%. Air contains 20.99% O2 by volume. Assume that the density of blood is 998 kg m -3 Part A Assuming that the Henry's law constant for blood is the same as for water (4.95 x 104 bar), calculate the amount of O₂ dissolved in 1.00 L of blood for pressure of 1.00 bar.

This question has multiple parts. Work all the parts to get the most points. Use the References to access important values if needed for this question. The Gibbs Free Energy equation is given by the equation: AG=AG + RTln Q - Where: AG = Gibbs Free Energy change AG = Standard Gibbs Free Energy change T= temperature In Q = natural log of the reaction quotient In order to solve for the temperature, T, in two steps you must: Step One Add the same expression to each side of the equation to leave the term that includes the variable by itself on the right-hand side of the expression: (Be sure that the answer field changes from light yellow to dark yellow before releasing your answer.) +AG = +AG + RT In Q Drag and drop your selection from the following list to complete the answer: 1 -AG AG AGⓇ AGⓇ Submit
