Answer

a) 0.31 b) 0.78 c) 0.92

Work Step by Step

For parts a-b use the equation: Y$_{O2}$ = $\frac{(pO_{2})^{n}}{(p_{50})^{n}+(pO_{2})^{n}}$ a) Y$_{O2}$ = $\frac{20^{3}}{26^{3} + 20^{3}}$ = $\frac{8,000}{17,576 + 8000}$ = 0.31 b) Y$_{O2}$ = $\frac{40^{3}}{26^{3} + 40^{3}}$ = $\frac{64,000}{17,576 + 64,000}$ = 0.78 c) Y$_{O2}$ = $\frac{60^{3}}{26^{3} + 60^{3}}$ = $\frac{216,000}{17,576 + 216,000}$ = 0.92
