Answer:
67.3 atm
Explanation:
We'll begin by converting 25 ℃ to Kelvin temperature. This can be obtained as follow:
T(K) = T(℃) + 273
T(℃) = 25 ℃
T(K) = 25 + 273
T(K) = 298 K
Finally, we shall determine the pressure. This can be obtained by using the ideal gas equation as illustrated below:
Gas constant (R) = 0.821 atm.L/Kmol
Volume (V) = 212 L
Number of mole (n) = 584 moles
Temperature (T) = 298 K
Pressure (P) =?
PV = nRT
P × 212 = 584 × 0.0821 × 298
P × 212 = 14288.0272
Divide both side by 212
P = 14288.0272 / 212
P = 67.3 atm
Thus, the pressure is 67.3 atm
