A mixture of three gases has a pressure at 298 K of 1380 mm Hg. The mixture is analysed and is found to contain 1.27 mol CO2, 3.
enot [183]

Answer:

The partial pressure of Ar is 356.04 mm Hg (= 0.4685 atm)

Explanation:

<u>Step 1:</u> Data given

A mixture of three gases has a total pressure of 1380 mm Hg (=1.81579 atm) at 298 K

Moles of CO2 = 1.27 moles

Moles of CO = 3.04 moles

Moles of Ar = 1.50 moles

<u>Step 2:</u> Calculate total number of moles

Total number of moles = n(CO2)+ n(CO)+ n(Ar) = 1.27 mol+ 3.04 mol+ 1.50 mol = 5.81 moles

<u>Step 3:</u> Calculate mol fraction Ar

Mol fraction Ar = 1.50 mol/5.81 mol = 0.258

<u>Step 4</u>: Calculate partial pressure

1380 mm Hg * 0.258 moles Ar = 356.04 mm Hg = 0.4685 atm

The partial pressure of Ar is 356.04 mm Hg (= 0.4685 atm)

If you remove the cap of a bottle of a soft drink carbon dioxide escapes the soft drink but the soft drink is still a solution.
Effectus [21]

Answer:

Removing the cap from a soft drink bottle releases pressure and causes the excess carbon dioxide molecules to come out as bubbles. however the drink is still supersaturated , and will release that carbon dioxide till it goes flat
