Answer:
8.69 mol.
Step-by-step explanation:
- We can use the general law of ideal gas: PV = nRT.
where, P is the pressure of the gas in atm (P = 11.0 atm).
V is the volume of the gas in L (V = 12.0 L).
n is the no. of moles of the gas in mol (n = ??? mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = 185.0 K).
∴ n = PV/RT = (11.0 atm)(12.0 L)/(0.0821 L.atm/mol.K)(185.0 K) = 8.69 mol.
