Answer 2

`T=404.16K=13.1^oC`

Step-by-step explanation:

Hello,

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

`PV=nRT\\T=(PV)/(nR)=(1950mmHg*(1atm)/(760mmHg)*15500mL*(1L)/(1000mL) )/(1.2mol*0.082 (atm*L)/(mol*K) ) \\T=404.16K=13.1^oC`

Best regards.
