Atmospheric pressure at sea level is 760 mm Hg, and oxygen makes up 20.9% of this air when it is dry. Scientists at the Mt. Wash

Lubov Fominskaja [6]

Answer:

127.28 mmHg

Explanation:

The molar fraction of oxygen in dry air at 760 mmHg is 20.9%. This molar fraction is not affected too much by the height, so it may be taken as a constant. The partial pressure of oxygen may be calculated as:

$P_{O_{2}}=y_{O_{2}}*P$

So, if the total pressure is 609 mmHg,

$P_{O_{2}}=0.209*609=127.28$ mmHg.

Answer:

The correct answer is 2.33g of $H_{2}O$ , A

Explanation:

We can use basic stoich to get this question.

To start, lets convert our grams to moles in order to use our equation. 5.38g of $O_{2} = (\frac{5.38}{2*15.999}) moles = 0.168136$ moles.

We then can use our molar ratio of 13:10. Simply divide by our molar ratio in order to go from moles of $O_{2}$ to moles of $H_{2}O$ . This gets us 0.129335 moles of $H_{2}O$ .
