Answer:
Ideal gas equation.
Explanation:
Given that:
Pressure = 101.325 kPa
Also, P (kPa) = 1/ 101.325 atm
So, pressure = 1 atm
Temperature = 50°C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T = (50 + 273.15) K = 323.15 K
Volume = ?
n = 3.2 mole
Using ideal gas equation as:
PV=nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
1 atm × V = 3.2 mol × 0.0821 L.atm/K.mol × 323.15 K
⇒V = 84.89 L
