Hello!
The answer is: 4.77atm
Why?
Since there's a fixed volume, we can use the the Gay-Lussac's Law which stablish a relation between the pressure and the temperature:
[tex]\frac{P}{T}=k[/tex]
P is the volume of the gas
t is the temperature of the gas
k is the proportionality constant
We also have the following equation:
[tex]\frac{P1}{T1}=\frac{P2}{T2}[/tex]
Where:
[tex]P2=\frac{P1*T2}{T1}=\frac{317kPa*235K}{154K}=483.73kPa[/tex]
We are asked to find the pressure in atm, so we must convert 483.73kPa to atm:
[tex]1kPa=0.009869atm[/tex]
Then,
[tex]483.733kPa*\frac{0.009869atm}{1kPa}=4.77atm[/tex]
Have a nice day!
