A gas cylinder containing 1.50 mol compressed 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? (R = 0.08206 L • atm/K • mol) A) 9.00 × 10^-2 atm B) 0.933 atm C) 1.11 atm D) 1.70 atm E) 11.1 atm

To find the pressure exerted by the methane gas, we can use the ideal gas law equation, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin. First, convert the temperature to Kelvin: T = 25°C + 273.15 = 298.15 K. Then, plug in the values: P = (nRT)/V = (1.50 mol * 0.08206 L•atm/K•mol * 298.15 K) / 3.30 L = 11.1 atm.
