Question:
Calculate the temperature of 4.0 mol of a gas occupying 5 dm³at 3.32 bar.

(R = 0.083 bar dm³ K^–1 mol^–1).

Answer:

Given,

Amount of the gas, n = 4.0 mol

Volume of the gas, V = 5 dm³

Pressure of the gas, p = 3.32 bar

R = 0.083 bar dm³ K^–1 mol^–1

From the ideal gas equation, we get

pV = nRT

⇒ T = pV / nR

= (3.32x5) / (4x0.083)

= 50K

Hence, the required temperature is 50 K.
