If five moles of a gas at a pressure of 5.4 kpa have a volume of 120 liters, what is the temperature?

Explanation:

Given parameters:

number of moles of gas = 5 moles

pressure on the gas = 5.4kpa

volume of gas = 120L

Unknown:

temperature of the gas = ?

Solution:

To solve this problem, we have to apply the ideal gas law.

The law is derived from the combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.

 Combining the laws, we have;

                  PV = nRT

where P is the pressure in atm

           V is the volume

           n is the number of moles

           R is the gas constant 0.082atm dm³ mol⁻¹ K⁻¹

          T is the temperatue in kelvin

Now, we must convert the pressure from kpa to atm;

          1 atm = 101.325kpa

                5.4kpa;

                              = 0.053atm

    Input the parameters;

            0.053 x 120 = 5 x 0.082 x T

                   T = 15.5K

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
