A compressed gas cylinder containing 1.50 mol methane has a volume of 3.30 L.What pressure does the methane exert on the walls of the cylinder if its temperature is 25°C?

Question

Quizplus · Accepted Answer

Using the ideal gas law, PV = nRT, where P is pressure, V is volume, n is moles, R is the ideal gas constant (0.0821 L·atm/mol·K), and T is temperature in Kelvin. Convert 25°C to Kelvin (298 K) and solve for P: P = (1.50 mol * 0.0821 L·atm/mol·K * 298 K) / 3.30 L = 11.1 atm.
