A sample of dry air contains 210 mL of oxygen 780 mL of nitrogen and 10.0 mL of all other gases What is the pressure in mm of Hg due to the nitrogen if the total pressure was 1000.0 mm?

Dalton says: "The partial pressure of a (non-condensing) gas in the mixture is proportional to its concentration." Since your total pressure is 1000 mmHg and the volumes all total to 1000 mL, you don't even need to take your shoes off to do the math.
The nitrogen's volume is 780 ml of the total 1000 ml so its partial pressure is 780 mmHg of the total 1000 mmHg.

If a sample of air that has a total pressure of 150 ATM contains 69 oxygen what is the partial pressure of oxygen found within the air?
The pressure is 103,5 at.
If the temperature is increased What happens to the partial pressure of oxygen in a sample of air?
In a sample of air, an increase in temperature will result in an increase in the partial pressure of oxygen.
How many milliliters of nitrogen and oxygen are in a one liter sample of dry air?
781ml of N2 and 209ml of O2
A sample of oxygen gas has a volume of 150 milliliters at 300k if the pressure of the sample is held constant and the temp raised to 600k the new sample will be?
300. mL
A sample of oxygen gas occupies 320.0 mL at 27C and atmospheric pressure What volume does it occupy at 120C and the same pressure?
419 mL
If a sample of air that has a total pressure of 150 ATM contains 69 oxygen what is the partial pressure of oxygen found within the air?
The pressure is 103,5 at.
If the temperature is increased What happens to the partial pressure of oxygen in a sample of air?
In a sample of air, an increase in temperature will result in an increase in the partial pressure of oxygen.
A sample of ascorbic acid contains 1.50 of carbon and 2.00 of oxygen while another sample of ascorbic acid contains 6.35 of c. How many grams of oxygen does it contain?
23
How do you distinguish between nitrogen oxide and oxygen using a chemical test?
Use a sample of pyrogallol (C6H6O6) in the sample followed by a combustion reaction. This compound absorbs oxygen present.
Is a sample of nitrogen and oxygen in the same container homogeneous?
It would be freely mixed, so yes.
A sample of nitrogen gas is collected over water at 20 degrees Celsius. The vapor pressure of water at 20 degrees Celsius is 18 mmHg. What is the partial pressure of the nitrogen if the total pressure?
747 mmHg
What if oxygen is removed from a sample of air as iron rusts what happen to the partial pressure of oxygen in the air?
it decreases
A 110.0 mL sample of nitrogen at 820 torr was compressed to a volume of 83.0 mL in a syringe What was the pressure of trapped nitrogen in torr?
1100
A 100.0 mL sample of nitrogen at 810 torr was compressed to a volume of 72.0 mL in a syringe What was the pressure of trapped nitrogen in torr?
1100
If 230 g sample of a compound contains 136.6 g of carbon 26.4 g of hydrogen and 31.8 g of nitrogen The rest is oxygen What is the mass percent of oxygen in the compound?
The mass of the elements that are not oxygen equals 194.8g. The mass of oxygen is 230g - 194.8g = 35.2g of oxygen. Mass percent of oxygen = 35.2g O/230g x 100 = 15% O
A 125.0 mL sample of nitrogen at 790 torr was compressed to a volume of 75.0 mL in a syringe What was the pressure of trapped nitrogen in torr?
1300<--- torr
