The mass will be 24kg.
The mass of an object does not depend on its location, the local gravity field or its acceleration. The mass is an intrinsic property of the object which does not change.
The weight of an object is defined by Newton’s 2nd Law of Motion, and is the product of the mass and its acceleration. If you take the acceleration to be 1g, then the weight (in kg force) is numerically equal to its mass (in kg).
The difference between mass and weight was not understood in olden days and, unfortunately, the same name was used for units of mass and weight. In SI units, the weight of an object is the product of the mass (in kg) and acceleration (in m/s^2) and the unit is the Newton
A mass of 24kg on Earth would, therefore, weigh 24 * 9.81 Newtons. On the moon, the weight would be 24 * 1.625 Newtons.
