    In order to calculate the final volume of the gas, we may apply Charles Law, which states that for a fixed amount of gas subject to a fixed amount of pressure, the volume and temperature of a gas are directly proportional. This is:

    V/T = constant

    Using this equation,

    5/298 = V/278

    V = 4.66 L

    The final volume of the gas is 4.66 liters
