The concentration of O₂ in blood is 1.0×10^{- 2} molal. At 37 ° C (body temperature), Henry's law constant for oxygen is 1.8×10^{- 3} molal/atm. What is the apparent pressure of O₂ (in atmospheres) in contact with the blood?

Question

Quizplus · Accepted Answer

The apparent pressure of O₂ can be calculated using Henry's law: P = C / k, where C is the concentration (1.0×10⁻² molal) and k is the Henry's law constant (1.8×10⁻³ molal/atm). Thus, P = (1.0×10⁻²) / (1.8×10⁻³) = 5.6 atm.
