Answer:
= 129.06 moles
Step-by-step explanation:
Using the ideal gas equation;
PV = nRT
Where; P is the pressure, V is the volumes, n is the number of moles, R is the ideal gas constant and T is the temperature.
In this case; V = 12.5 L, P = 25325 kpa or 249.94 atm, T = 22 + 273 = 295 K and R= 0.08206L atm/mol K
n = PV/RT
= (12.5 × 249.94)/(0.08206 × 295)
= 129.06 moles
