What is the temperature of 2.33 mols of an unknown gas that is in a 4.5 L container with an internal pressure of 4.55 kPa?

Answer:

temperature = 1.05 K

Explanation:

We are told to find the temperature of a 2.33 mol gas that has a volume of 4.5 L with a pressure of 4.55 kPa.

To solve this problem, we need to use the ideal gas law. which is expressed in the formula:

[tex]\boxed{PV = nRT}[/tex],

where:

• P = pressure in Pascals

• V = volume in m³

• n = number of moles

• R = molar gas constant (8.31 J/K · mol)

• T = temperature in Kelvin (K)

First, let's convert the pressure and volume into the units required by the formula:

○ pressure = 4.55 kPa = 4550 Pa     (multiplying by 1000)

○ volume = 4.5 L = 0.0045 m³    (dividing by 1000)

Now we can substitute this data into the above formula and solve for T:

[tex]PV = nRT[/tex]

⇒ 4500 × 0.0045 = 2.33 × 8.31 × T

⇒ 20.25 = 19.3623T

T = [tex]\frac{20.25 }{19.3623}[/tex]

T = 1.05 K  (3 s.f.)

Therefore, the temperature of the gas is 1.05 K.
