how do u find an object's density in a graduated cylinder if the water level raises from 25.1 mL to 30.1mL.?

density=mass/volume
here volume=5 ml for the object
In your question you have to find out the mass of object on your own.
You can use Formula of bauyance( sorry i don't remmember the formula because i had read it almost 4 years ago.
bye
take care

Mass is basically the amount of matter in an object and is measured in kilograms (or grams). Weight is really a measure of the pull of gravity on an object, so it's a mass under the influence of gravity. With density, you are dealing with mass in grams.
If you take a graduated cylinder and put water in it, you can add an object and measure the displacement. For example, find the mass of a rubber stopper. Put 50 ml of water in a 100 ml graduated cylinder. Drop the stopper into the graduated cylinder. The new volume minus the 50ml is the volume of the stopper.
Divide the mass of the stopper in grams by the volume in ml (by the way, 1 ml of water= 1 cubic centimeter of water), and you will have the density for the stopper.

The density of your object will be the difference between the original level of water and the level it became after you added your object. If original level is A and B is the water level after you added your object then B - A = Density of Object. Now it's your turn to do the math :)

density=mass divide by volume
Find the mass of the cylinder and use the above formula to calculate the density.
