Answer:

[tex]T=404.16K=13.1^oC[/tex]

Explanation:

Hello,

In this case, we use the ideal gas equation to compute the requested temperature as shown below and considering the proper units:

[tex]PV=nRT\\T=\frac{PV}{nR}=\frac{1950mmHg*\frac{1atm}{760mmHg}*15500mL*\frac{1L}{1000mL} }{1.2mol*0.082 \frac{atm*L}{mol*K} } \\T=404.16K=13.1^oC[/tex]

Best regards.
