by size,volume and gravity
You cannot.
The weight is the mass multiplied by the acceleration of gravity. When weighing an object by a balance the acceleration of gravity is on both sides of weighing and hence canceling its effect and hence you get the object mass (not the weight)..

The device used for comparing the mass of an object to a known mass is a double pan balance, or a balance scale. This is a type of weighing scale where you put weights on one pan and the substance you are weighing on the other.
You compare its mass with something of known mass. In everyday earthbound conditions, this would mean weighing it on a set of weighing scales or on a spring balance.
The only "weigh" to determine the mass of an object is to compare it with the mass of a known object. The mass of an object is determined by force and acceleration.
The mass divided my the volume determine the density of an object
Without knowing its mass, you can't determine its density. But if it's in water, you can make one broad distinction regarding its density: If the object is floating, then its density is less than ' 1 '. If the object sank, has sunk, or is sinking, then its density is more than ' 1 '.
On an electronic weighing scale or just any weighing scale. Place an object (may be an eraser). In order for the mass to disappear, the weight should come to zero. Remove the eraser form the weighing scale. From this experiment you can see that for there to be no mass there is to be no object too. If you're also talking about the mass of air, then there would be no gravitational force between the two objects.
This is often achieved by weighing it. In this case, it may be compared with the weight of a standard (i.e., known) mass.
