How many moles of methane occupy a volume of 2.00 l at 50.0°c and 0.500 atm answer?
1 answer:
Data Given: Pressure = P = 0.5 atm Volume = V = 2.0 L Temperature = T = 50 °C + 273 = 323 K Moles = n = ?Solution: Let suppose the gas is acting Ideally, Then According to Ideal Gas Equation . P V = n R T Solving for n, n = P V / R T Putting Values, n = (0.5 atm × 2.0 L) ÷ (0.0821 atm.L.mol⁻¹.K⁻¹ × 323 K) n = 0.0377 mol
