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.

Convert 645 Newtons per quart to tons per liter. (The picture is a conversion table for help)
brilliants [131]

Answer:

0.067 ton/Litre.

Explanation:

645 Newtons per quart to tons per liter.

We'll begin by converting 645 Newton/quart to gram/quart (g/q). This can be obtained as:

1 N/q = 100 g/q

Therefore,

645 N/q = 645 N/q × 100 g/q / 1 N/q

645 N/q = 64500 g/q

Therefore, 645 Newton/quart is equivalent to 64500 grams per quart.

Next, we shall convert 64500 grams per quart to pounds per quart. This can be obtained as follow:

454 g/q = 1 pound/q

Therefore,

64500 g/q = 64500 g/q × 1 p/q / 454 g/p

64500 gram/quart = 142.07 pound/quart

Therefore, 64500 gram/quart is equivalent to 142.07 pound/quart.

Next, we shall convert 142.07 pound/quart to ton/quart. This can be obtained as follow:

2000 p/q = 1 ton/q

Therefore,

142.07 p/q = 142.07 pq × 1 ton/q / 2000 p/q

142.07 pound/quart = 0.071 ton/quart

Therefore, 142.07 pound/quart is equivalent to 0.071 ton/quart.

Finally, we shall convert 0.071 ton/quart to ton/litre. This can be obtained as follow:

1 ton/q = 1/1.06 ton/L

Therefore,

0.071 ton/q = 0.071 ton/q × 1/1.06 ton/L / 1 ton/q

0.071 ton/quart = 0.067 ton/Litre

Therefore, 0.071 ton/quart is 0.067 ton/Litre.

From the above illustration, 645 Newton/quart is equivalent to 0.067 ton/Litre.

What material makes up ash and pumice?
slamgirl [31]

Pumice rocks are formed due to the air that is trapped in between the rocks, a body of magma spurting out with dissolved gas under pressure. As the magma cracks through the Earth’s surface, the sudden pressure drop causes the gas to come out of the solution. The flash of gas form the vent slices the magma and blows it out as a molten lather. The lather hastily solidifies as it flies into the air and falls back to Earth as pieces of pumice.
