What is the mole fraction of o2 in the flask?

The mole fraction of O2 in the flask is 0.341.

What is the partial pressure of o2 in the mixture?

The partial pressure of O2 is 0.426 atm.

What is the mole fraction of n2 in the mixture?

The composition by mole fraction of N2 is 0.147.

How do you find the mole fraction?

The mole fraction formula for a solution with containing one or more solutes is: Mole fraction of each solute = Number of moles of that solute divided by the total number of moles of all solutes and the solvent.

What is the formula for moles of a gas?

A mole of any substance has a mass in grams equal to its molecular weight, which can be determined from the periodic table of elements. The ideal gas law can also be written and solved in terms of the number of moles of gas: PV = nRT, where n is number of moles and R is the universal gas constant, R = 8.31 J/mol ⋅ K.

What is the partial pressure of O2 in Torr?

159.6 torr .
Partial pressure of oxygen can be represented as PO2 P O 2 . The partial pressure of oxygen in the atmosphere is 159.6 torr .

What is the mole fraction of N2 and O2?

0.700
In a mixture of N_(2) and O_(2) gases, the mole fraction of N_(2) is found to be 0.700. the total pressure of the mixture is 1.42atm.

Is N2 and O2 a mixture?

Oxygen – nitrogen gas mixture is a colorless odorless gas. Both oxygen and nitrogen are noncombustible; however, oxygen can accelerate the burning of a fire.

What is the formula for a mole?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

What is the partial pressure of oxygen in the flask?

When the partial pressure of the oxygen is 78.00 mm of mercury, what is the total pressure in the flask? 2.0/ 12.0 = 0.167 of the total pressure. 78.00 is to 0.167 as the total pressure is to one, so 468 mmHg is the answer. 72. A flask contains 2.00 moles of nitrogen and 2.00 moles of helium.

How much pressure is in a flask of nitrogen gas?

2.0/ 12.0 = 0.167 of the total pressure. 78.00 is to 0.167 as the total pressure is to one, so 468 mmHg is the answer. 72. A flask contains 2.00 moles of nitrogen and 2.00 moles of helium.

How many grams of hydrogen are in a flask of oxygen?

A mixture of 14.0 grams of hydrogen, 84.0 grams of nitrogen, and 2.0 moles of oxygen are placed in a flask. When the partial pressure of the oxygen is 78.00 mm of mercury, what is the total pressure in the flask?

How do you find the mole fraction of a gas?

If the mole fraction of a gas was 0.15, then its partial pressure would be 0.15 times the total pressure. The reverse is also true. If you divided the partial pressure of a gas by the total pressure, you would get the mole fraction for that gas.
