A 34.5-g gold is dropped into a graduated cylinder containing water by how many milliliters does the measured volume increase?
34.5/19.3=1.79mL (19.3 is the density of gold)
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.
A graduated cylinder has 32.0 mL of water in it A 3.0 cm3 rock is dropped into the graduated cylinder What is the new volume?
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).
Why do you have to wet the lead pellet before dropping it into the graduated cylinder when determining the volume?
When using a lead pellet to determine the volume of a liquid, the pellet is wet before being dropped into the cylinder so that it will sink faster. If the pellet was not wet it would take a fraction of a second to start to sink in the liquid.
A sample of a substance containing glycerin?
Nitroglycerin. It is a highly unstable explosive know for being detonated by a shockwave (dropped on floor).

What are some things that can happen if you drop a piece of metal into a graduated cylinder partially filled with water?
It could sink. (The metal's density is greater than water.) It could turn into a ball of flames. (If you dropped a chunk of sodium into graduated cylinder, it would react with flames or sparks.)
A body whose mass is 60 g is dropped into a cylinder containing 150mL of water. The water rises to the 200mL mark. What is the density of the body?
50 ml.
If you have a graduated cylinder that contains ml of water you drop a rock into the cylinder and the water level rises to ml the mass of the rock is grams what is the rocks density?
density = mass/volume → The density of the rock is the mass of the rock divided by the difference in the volume from before the rock was dropped in and afterwards. Its units are grams/ml
If the mass of an object is weigh and the object is dropped in cylinder containing water but the object is not fully under water will this affect the density?
The density of what? But regardless the answer to that: Density is mass per volume. Mass is not influenced by the upward force of the fluid in which the object is submerged. The weight, on the other hand, is. Weight is a force, and mass is an amount of matter.
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?
65 - 40 = 25 ml
What year Lisa Lopes graduated?
She dropped out.
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.
When did bill gates graduate from Harvard university?
He graduated from High School in 1964. He dropped out of Harvard (never graduated).
Can you calculate the volume of an item without knowing the density?
It is quite simple if it is a regular shaped object like a cylinder or a cube. For example if you wanted calculate the volume of a cylinder you need to know the radius of the circular cross-section of the cylinder - this is the measurement from the centre of the circle, to the outer-edge and then multiply that by the height of the cylinder. For irregular shaped objects don't think there is a simple mathematical way if you don't know the density but you can always use water displacement to get a volume measurement. Just drop the object you want to know the volume off into a graduated cylinder partially filled with water - the amount the level rises will be roughly equal to the volume of the object you dropped in.

What is the definition of a graduated cylinder?
A graduated cylinder is a piece of laboratory equipment used to accurately measure the volume of an object. Graduated cylinders are generally more accurate and precise for this purpose than flasks and beakers.A graduated cylinder, also known as a measuring cylinder is a piece of laboratory equipment used to accurately measure the volume of an object. Water displacement can be used to find out the volume of an object. Graduated cylinders are generally more accurate and precise for this purpose than flasks and beakers. Often, the largest graduated cylinders are made of polypropylene for its excellent chemical resistance or polymethylpentene for its clarity, making them lighter to ship and less fragile than glass. Polypropylene cylinders have excellent chemical resistance and do not shatter when dropped, although one problem with this type of cylinder is that it can not be heated. Polypropylene is easy to repeatedly autoclave (sterilize); however, autoclaving of some polypropylene graduated cylinders may affect their accuracy.
