Question

What is the temperature of a 11.5 mol gas sample that it kept at 1.75 atm in a 47.2-L container?

Answer 1

By using standard Ideal Gas equation

$PV=nRT$ where $R$ is universal gas constant.

$R=0.0821L\ atm\ mol^{-1} K^{-1}$

On substituting values,

$1.75\times47.2=11.5\times0.0821\times T$

$\implies T=87.486\ K$
