A sample of hydrogen gas (H₂) has a volume of 17.4 L at a temperature of 0.00C and a pressure of 1.60 atm. The number of moles of H₂ molecules of hydrogen in the sample is

Question

Quizplus · Accepted Answer

Using the ideal gas law PV = nRT, where P = 1.60 atm, V = 17.4 L, R = 0.0821 L·atm/mol·K, and T = 273.15 K, the number of moles n = PV/RT = (1.60 * 17.4) / (0.0821 * 273.15) = 1.24 mol.
