How many moles of an ideal gas are there in a container with a pressure of 108,893 Pa,a temperature of 321 K,and a volume of 2.0 L? The universal gas constant is 8.314 J/K · mol.
A)0.082 mol
B)82 mol
C)5600 mol
D)11,000 mol

Using the ideal gas law PV = nRT, where P = 108,893 Pa, V = 2.0 L (converted to 0.002 m³), R = 8.314 J/K·mol, and T = 321 K, we solve for n (moles): n = PV/RT = (108,893 * 0.002) / (8.314 * 321) ≈ 0.082 mol.
