    W = 1.728×107 J
    Amount of energy absorbed = Work done
    = 1.728×107J
    The correct answer is: 1.728

    To calculate the energy absorbed by the gas, we can use the equation:

    ΔU = nCvΔT

    Where:
    ΔU is the change in internal energy of the gas
    n is the number of moles of the gas
    Cv is the molar specific heat capacity at constant volume of the gas
    ΔT is the change in temperature of the gas

    Given:
    P1 (initial pressure) = 8 atm
    P2 (final pressure) = 4 atm
    T (constant temperature) = 27 °C = 27 + 273 = 300 K
    Mass of the gas (m) = 10 kg
    Molar mass of the gas (M) = ? (Not provided)

    To calculate the molar mass (M) of the gas, we can use the formula:

    M = m / n

    Where:
    m is the mass of the gas
    n is the number of moles of the gas

    To find the number of moles (n) of the gas, we can use the formula:

    n = m / M

    Let's calculate the molar mass (M) of the gas:

    M = m / n
    M = 10 kg / n

    Now, we need to find the number of moles (n) of the gas. To do that, we need the molar mass of the gas. Since the molar mass is not provided, we cannot calculate the number of moles and, consequently, the energy absorbed by the gas.

    Therefore, we cannot determine the energy (in 10^7 Joules) absorbed by the 10 kg molecule of the ideal gas without the molar mass of the gas.
