The correct answer is B.The ideal gas law can be used to calculate the temperature of the chlorine gas. The ideal gas law is 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.We can rearrange the ideal gas law to solve for T: T = PV/nR.We know the pressure, volume, and number of moles of chlorine gas. We can look up the value of the ideal gas constant, which is 0.0821 L*atm/(mol*K).Plugging in our values, we get: T = (800 mm Hg * 1 atm/760 mm Hg) * 40.0 L / (100.0 g * 1 mol/70.9 g/mol) * 0.0821 L*atm/(mol*K) = 364 K.Converting to Celsius, we get: T = 364 K - 273.15 = 91°C.
