It could be two items of the same size, but made out of different materials, for instance, one made of aluminum, and another made of iridium.
cause the two have lost their weight
The reason is because the mass is like the volume and the weight is like how heavy an object is.
Inertia is "rotary momentum"; an object's ability to continue spinning when a decelerating force is applied.Just as a heavy object takes more effort to stop from the same speed as a light object, so does a heavy object take more effort to stop from turning at the same speed as a light object.So assuming they are turning at the same angular velocity, the heavier one has a larger inertia. Otherwise, remember that inertia is also proportional to angular velocity.
Measure the volume of the object which is same as the volume of the displaced liquid in which that sinks. And measure the mass of the same object from a weighing machine. then use density = mass/volume
-- Because that's the way gravity behaves. -- Because is would be ridiculous to think that heavy objects fall faster. Here's why: ==> Let's say that heavy objects fall faster and light objects fall slower. ==> Take a piece of sticky tape and stick a light object onto the back of a heavy object. Then drop them together off of a roof. ==> The light object tries to fall slower and holds back, and the heavy object tries to fall faster and pulls forward. So when they're stuck together, they fall at some in-between speed. ==> But wait! When they're stuck together they weigh more than the heavy object alone. So how can a stuck-together object that's heavier than the heavy object alone fall at a speed that's slower than the heavy object alone ? ! ? Isn't that ridiculous ? There's no way that heavy objects can fall faster than light objects.

drop a heavy object and a light object from the same height at the same time. time it with a stopwatch, or just watch them.
About 10% more for the same volume.
A block of light balsa wood and a block of heavy teak of the same size, will also have the same volume (which is the space each block occupies).
The heaviness of each particle. For example, a rock is made of heavier particles than a piece of cloth so if you were to get the same quantity of each item and drop it, than the rock would hit the ground first since it is more dense. An improved version: Density is a measurement that describes how heavy an object is for a given volume. For example: an object has high density if it is heavy and has a small volume (e.g. gold), and an object has low density if it is light and has a large volume (e.g. balloon).
They are exactly the same amount
Inertia is "rotary momentum"; an object's ability to continue spinning when a decelerating force is applied.Just as a heavy object takes more effort to stop from the same speed as a light object, so does a heavy object take more effort to stop from turning at the same speed as a light object.So assuming they are turning at the same angular velocity, the heavier one has a larger inertia.

Why, I don't know! Let's think about the weight of the air in a jar, and compare it to the weight of a rock that would fill the same jar.
