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$\degree$C?

Question

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 = \frac{nRT}{V} = \frac{(1.50 \, \text{mol})(0.0821 \, \text{L·atm/mol·K})(298 \, \text{K})}{3.30 \, \text{L}} \approx 11.1 \, \text{atm} $.
