    0.113 m/s²

    Explanation:

    Acceleration due to an object's gravity is:

    g = GM / R²

    where G is the universal gravitational constant (6.67*10⁻¹¹ m³/kg/s²),

    M is the mass of the object,

    and R is the distance from the object's center of mass.

    Given M = 1.08*10²⁰ kg and R = 2.52*10⁵ m:

    g = (6.67*10⁻¹¹ m³/kg/s²) (1.08*10²⁰ kg) / (2.52*10⁵ m) ²

    g = 1.13*10⁻¹ m/s²

    The acceleration of gravity on the surface of Enceladus is 0.113 m/s².
