CO2 gas .... P1V1 / T1 = P2V2 / T2 ............ combined gas law V1 / T1 = V2 / T2 ..................... pressure is constant ... Charles's law V1 = V2T1 / T2 ........................ solve for V1 V1 = 766.9 mL x (77.0 + 273.15)K / (154 + 273.15)K V1 = 628.7 mL Doubling the Celsius temperature is not the same as doubling the absolute temperature.
