Question

At an atmospheric pressure of 870 mm Hg with 21 percent oxygen, the partial pressure of oxygen is _____.A) 219 mm HgB) 127 mm HgC) 151 mm HgD) 182 mm HgE) 100 mm Hg

Answer 1

d) 182 mm Hg

Step-by-step explanation:

The ratio of partial pressure to total pressure is equal to the molar ratio.

P / 870 mm Hg = 0.21

P = 182 mm Hg

Answer is D.
