The rock's volume is simply the amount of water the rock displaced (52mL - 32mL), so 20mL.

The density is mass over volume, so 40g/20mL, which simplifies to 2 g/mL:

40 divided by 20 is 2, and then the unit is just mass (g) over volume (mL).

What do you call the procedure that helps you determine the volume of an irregularly shaped object while using a graduated cylinder?

displacement - invented by Archimedes. Completely fill a large volume of something with water. Have a spout to channel all excess water. Place a graduated cylinder under the spout. Place irregular object in the large volume filled with water. The volume of the irregular object will displace an equivalent volume of water into the graduated cylinder. The measured volume in the cylinder is the volume of the irregular object.


If an object floats in a beaker as shown assuming the graduated cylinder was empty when the object was placed in the beaker and the beaker was full to the level of the spout what must be true?

stop cheating on gizmos, fool. :)The Answer: The mass of the water in the graduated cylinder is equal to the mass of the object.lol


Are correct procedures for reading the volume of water in the graduated cylinder?

Water in a glass graduated cylinder adheres to the sides of the cylinder, forming a meniscus which is an upward curve. When reading volume in a cylinder, look at the meniscus at eye level. Read the volume at the bottom of the curve.


To find the density of an object you would use a graduated cylinder to find what characteristic of the object?

You can use a graduated cylinder to measure an object's volume.Fill the cylinder with water up to some convenient mark that's deeper than the object, and notethe volume of water in the cylinder. Than immerse the object in the water in the cylinder and notethe volume again. The difference between the two volume readings is the volume of the object.In my house, we have graduated cylinders which we refer to as our "measuring cups".


How can you calculate the volume of an irregularly shaped object?

If the object in question is water proof, and small enough. You can measure the amount of displaced water when it is placed in a tank full of water, this may not work for a lot of things but it can help when attempting to measure some objects.

If A heart shaped jewelry gold charm is dropped into a graduated cylinder filled at 20ml after it was dropped the water level increased to 25ml what is the volume of the charm?

5 ml. Just do the volume after minus the volume before. This is the water displacement method.


How do I find the volume of an irregular object using a graduated cylinder?

To find the volume of an irregular object using a graduated cylinder, you can use the method of water displacement. Fill the graduated cylinder with a known volume of water, then carefully submerge the irregular object in the water. The increase in water level corresponds to the volume of the object. Subtract the initial volume from the final volume to determine the volume of the irregular object.


What is a graduated cylinder for in science?

A graduated cylinder is used to measure the volume, or capacity of water. Or to just measure Water.


What is the volume of an object if you dropped a graduated cylinder and the water in the cylinder went from 40 ml to 65 ml?

How can you measure the volume of solid with a graduated cylinder?

You can put water in the graduated cylinder and drop the solid in and see how much the water rises


What method is the best way to find the volume of a sample of water?

Use a graduated cylinder and the water displacement method. Pour the sample of water in the graduated cylinder and find its meniscus. That is its volume.

Calculate the density of water using a graduated cylinder?

not quite. you can measure volume in a graduated cylinder. you can use a scale, water, and a graduated cylinder to find out the density of an object by filling the graduated cylinder to an easily calculated point (250) then dropping your object in the water making sure none splashes out then measure the difference, then weigh it and divide the mass by volume to get density.
