A newly discovered planet has an atmospheric pressure of 900 mm/Hg. The oxygen concentration is 18%. What is the pO2

162 mmHg

Explanation:

Step 1: Given data

Atmospheric pressure (P): 900 mmHg

Oxygen concentration: 18%

Step 2: Calculate the partial pressure of oxygen (pO₂)

In a gaseous mixture, an oxygen concentration of 18% corresponds to a mole fraction of X(O₂) = 0.18. We can calculate the partial pressure of oxygen using the following expression.

pO₂ = P × X(O₂)

pO₂ = 900 mmHg × 0.18 = 162 mmHg

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
