A sample of oxygen gas was collected via water displacement. Since the oxygen was collected via water displacement, the sample i

s saturated with water vapor. If the total pressure of the mixture at 26.4 °C is 805 torr, what is the partial pressure of oxygen? The vapor pressure of water at 26.4 °C is 25.81 mm Hg.

Answer :  The partial pressure of oxygen is, 799.19 torr

Solution :

According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.

P_T=p_{H_2O}+p_{O_2}

where,

P_T = total partial pressure = 805 torr

P_{O_2} = partial pressure of oxygen gas = ?

P_{H_2O} = partial pressure of water = 25.81 mm Hg = 25.81 torr

Now put all the given values is expression, we get the partial pressure of the oxygen gas.

805\text{ torr}=25.81\text{ torr}+p_{O_2}

p_{O_2}=779.19\text{ torr}

Therefore, the partial pressure of oxygen gas is, 799.19 torr

If 88.0 L of natural gas, which is essentially methane (CH4), undergoes complete combustion at 720. mm Hg and 22ºC, how many gra
mr_godi [17]

126 grams of H2O is formed.

Explanation:

Data given:

volume of the gas = 88 Liters

pressure = 720 mm Hg or 0.947 atm

temperature T = 22 Degrees or 295.15 K

R = 0.08021 atm L/mole K

n =?

The formula is used is of ideal gas law to know the number of moles of CH4 undergoing combustion.

PV = nRT

n = \frac{PV}{RT}

putting the values in the equation

   = 0.947 X 88/ 0.08021 X 295.15

n = 3.5 moles

balanced reaction for combustion of methane

CH4 + O2  ⇒ CO2 + 2H20

1 mole of CH4 undergoes combustion to form 2 moles of water

3.5 moles will give x moles of water

2/1 = x/3.5

x =  7 moles of water  (atomic mass of water = 18 gram/mole)

mass = atomic mass x number of moles

mass = 18 x 7

          =126 grams of water is formed.
