Carbon monoxide is a poisonous gas that is formed as a by-product of incomplete combustion. What pressure does 1.52 moles of this gas exert upon its surroundings if it is contained in a 42.5 L vessel at 65 ° 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 65 °C to Kelvin (65 + 273.15 = 338.15 K) and solve for P: P = (1.52 mol)(0.0821 L·atm/mol·K)(338.15 K) / 42.5 L = 0.992 atm.
