    1188.0 mL.

    Explanation:

    We can use the general law of ideal gas: PV = nRT.

    where, P is the pressure of the gas in atm.

    V is the volume of the gas in L.

    n is the no. of moles of the gas in mol.

    R is the general gas constant,

    T is the temperature of the gas in K.

    If n and P are constant, and have two different values of V and T:

    V₁T₂ = V₂T₁

    V₁ = 900 mL, T₁ = 27.0°C + 273 = 300.0 K.

    V₂ = ? mL, T₂ = 123.0°C + 273 = 396.0 K.

    ∴ V₂ = V₁T₂/T₁ = (900 mL) (396 K) / (300.0 K) = 1188.0 mL.
