Data:
p (pressure) = 81.8 kPa = 81.8*10³ Pa ≈ 8.07 atm
v (volume) = ? (in L)
n (number of mols) = 0.352 mol
R (Gas constant) = 0.082 (atm*L/mol*K)
T (temperature) = 25ºC converting to Kelvin, we have:
TK = TC + 273 → TK = 25 + 273 → TK = 298
Formula:
![p*V =n*R*T](https://tex.z-dn.net/?f=p%2AV%20%3Dn%2AR%2AT)
Solving:
![p*V =n*R*T](https://tex.z-dn.net/?f=p%2AV%20%3Dn%2AR%2AT)
![8.07*V = 0.352*0.082*298](https://tex.z-dn.net/?f=8.07%2AV%20%3D%200.352%2A0.082%2A298)
![8.07V \approx 8.60](https://tex.z-dn.net/?f=8.07V%20%5Capprox%208.60)
![V \approx \frac{8.60}{8.07}](https://tex.z-dn.net/?f=V%20%5Capprox%20%20%5Cfrac%7B8.60%7D%7B8.07%7D%20)
