Question

A sample of a gas occupies 5.0 L at STP. What will be the volume if the temperature is set to 320K at a pressure of 1.2 atm? 

Answer 1

We write mendeleev-Clayperon equation for non-standard conditions

$\frac{P_1V_1}{T_1}= \frac{P_2V_2}{T_2}.$ Where $P_1V_1T_1=STP$

$V_2=\frac{1.013×10^3×5×320}{121590×273}=4.883L$
