    Answer: 79.0 x 10²³ kg

    Explanation:

    The weight of any mass, is given by the value of the attractive force that the mass of the planet exerts on it, and is given by the Newton's Universal Law of Gravitation:

    Fg = G m Mp / rp²

    If Fg = 25.74 N, we can solve for Mp, as follows:

    Mp = Fg. rp² / G m = 25.74 N. (7.3 10⁶) ² m² / 6.67259. 10⁻¹¹ N. m² / kg². 2.6 kg

    Mp = 79.0 x 10²³ kg.
