Part b an "empty" container is not really empty if it contains air. how may moles of nitrogen are in an "empty" two-liter cola b
Sedbober [7]
<span>6.38x10^-2 moles
       First, let's determine how many moles of gas particles are in the two-liter container. The molar volume for 1 mole at 25C and 1 atmosphere is 24.465 liters/mole. So
   2 L / 24.465 L/mol = 0.081749438 mol
       Now air doesn't just consist of nitrogen. It also has oxygen, carbon dioxide, argon, water vapor, etc. and the total number of moles includes all of those other gasses. So let's multiply by the percentage of nitrogen in the atmosphere which is 78%
    0.081749438 mol * 0.78 = 0.063764562 mol.
        Rounding to 3 significant figures gives 6.38x10^-2 moles</span>

Oxygen gas is collected over water. The atmospheric pressure is 748 mmHg, and the temperature of the oxygen is 29 ºC. The pressu
KonstantinChe [14]

The pressure of the oxygen gas collected : 718 mmHg

<h3>Further explanation</h3>

Given

P tot = 748 mmHg

P water vapour = 30 mmHg

Required

P Oxygen

Solution

Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases

Can be formulated:

P tot = P1 + P2 + P3 ....

The partial pressure is the pressure of each gas in a mixture

P tot = P H₂O + P Oxygen

P Oxygen = 748 mmHg - 30 mmHg

P Oxygen = 718 mmHg
