Question

Calculate the temperature of 4.0 mol of a gas occupying 5 dm³ at 3.32 bar.

(R = 0.083 bar dm³ K^–1 mol^–1).

Answer 1

Given,

n = 4.0 mol

V = 5 dm³

p = 3.32 bar

R = 0.083 bar dm³ K^–1 mol^–1

The temperature (T) can be calculated using the ideal gas equation as:

pV = nRT

`=> "T" = ("pV")/("nR")`

`= (3.32xx 5)/(4xx0.083)`

= 50 K

Hence, the required temperature is 50 K.
