The weight on Mars would be 1.5 kg but the mass would still be 4.2 kg.

It's "mass" would still be 4.2 kg. However, it would only weigh about 1.7 kg.
Mass is mass, it does not change no matter where an object is. On the other hand, "weight" is dependant on the local force of gravity.

It would still be 4.2 kg because kilograms are a measure of mass. Mass is the same regardless of gravity. Pounds are a measure of force, which it would have less of.

Weight is a measurement that is dependent upon the existence of an acceleratory force, such as gravity.
Mass is the measurement of the quantity of the substance, irrespective to any sources of acceleration it might be under.
So, technically, your question cannot be answered.
If you meant how much would it's weight change in the Martian gravitational field, it would be about 1.5kg.
If you meant how much would it's mass change? None.

Mass is the same everywhere...It's only the weight that changes...
so the mass would still be 4.2 kg on Mars, but it's weight would change..
Weight on Earth = mass * acc. due to gravity = 4.2 kg * 9.8 m/s^2 = 41.16 N
Weight on Mars = mass * acc. due to gravity = 4.2 kg * 3.71 m/s^2 = 15.58 N
so if you divide weight on Mars by the acceleration due to gravity on Earth, you would get:
15.58 N/ 9.8 m/s^2 = 1.60 kg
Therefore, the weight on Mars would be 1.60 kg..

It's mass wouldn't change, but apparent weight would.
