mililiters
A small difference exist because the beaker is not calibrated for volume.
Approximately 1 gram/millilitre for the water, but not all small beakers of water have the same mass. In fact, it's much more likely the masses differ than are the same. Are you trying to fake a lab exercise or is this just a silly question?
Fill a beaker or measuring cylinder with water and record the volume of water indicated. Put the rock in the beaker/measuring cylinder and record the new volume of water indicated. The difference between the two volumes is the volume of the rock.
You need an analytical balance and a small beaker.
A small beaker.

to measure the small amount of volume
Volume displacement is the method used to find the volume of small or irregularly shaped objects by noting the difference in the level of liquid before and after after immersing an object into a graduated cylinder or beaker of liquid. For a small object immersed in a graduated cylinder or beaker, the volume displaced by the object can be read directly from the scale on the container.
There are a few types of equipments which measure small volume changes, which are known as volumeters. Small volume changes are measured with syringes, beakers, and volumenometers.

The volumes of small irregular solids are usually easily measured by measuring the volume of fluid displaced when they are immersed in a liquid. For example: You would have to put the object in a measuring glass with water in it. (~1/3 filled) Put the object in it and then get the number from the measuring glass (beaker etc. mostly beaker) and that is how you measure a irregular solid!
They can be used to measure the volume of liquids. Sometimes, they can also be used to measure the volumes of small, insoluble solids.
No, a beaker is a poor choice of instrument to measure volume. Instead try a graduated cylinder. Generally, the smaller the diameter of graduated cylinder, the more accurate it will be. A grad cylinder will have the increments written up along the side with carefully placed "hash marks" indicating the volume of substance/solution in the cylinder. A breaker may have a few markings indicating the volume of the contents up the side, but not enough make it an accurate measuring device for varying volumes of liquid.
I believe Archimedes came up with this... Fill a beaker or glass to the brim with water. Place the beaker in a bath, bowl or similar. Gently place the rock into the glass of water, allow the liquid to overflow into the bowl. The water displaced by the rock (which is now in the bowl and you can measure the volume of) is the volume of the rock. Hope this helps!
No, it isn't.
Volume displacement is the method used to find the volume of small or irregularly shaped objects by noting the difference in the level of liquid before and after after immersing an object into a graduated cylinder or beaker of liquid. The difference between the before and after levels of the liquid is the volume of an immersed object.
