∙ 14y agoThe volume of the piece of metal is measured by the difference in the volume of water in the graduated cylinder before and after the piece of metal is placed in the cylinder. This is stated to be 36 - 20 = 16 mL. Density is defined to be mass per unit volume. Therefore, for this piece of metal the density is 163/16 = 10 g/mL. (Only two significant digits are justified, because the is the number of significant digits in the limiting datum 16.)

∙ 14y agoNote the level of water in the graduated cylinder. Place the rock into the water carefully. Note the higher level to which the water rises. The difference between the old level and the new level is the volume displaced by the rock.
Level with the bottom of the fluid's meniscus
The level of the liquid in the cylinder rose by 10 mL when the rock was submerged in the liquid.
You put it on a scale or a triple-beam balance. It'll give you the mass. However, if you have the density of the rock, divide it by the volume to find the mass mathematically. You can also find the volume by the water displacement method, where you placed the rock in a graduated cylinder/beaker filled partially with water and record the difference between the original water level and the raised water level after placing the rock inside the container.
To determine the volume of an irregular object using graduated cylinders, you fill a graduated cylinder with water right to the top, then submerge the object in the water. Measure the water that overflows using a second graduated cylinder, and read the water level in it in cc's or cubic inches. That is the object's volume.
Graduated Cylinder - Marbles
The volume of the silicon chunk can be calculated by subtracting the initial water level from the final water level in the graduated cylinder: 28.76 mL - 25.00 mL = 3.76 mL. Thus, the density of the silicon chunk is its weight (8.763 g) divided by its volume (3.76 mL), which equals approximately 2.33 g/mL.
The Volume of the rock is 7-2=5 ML then the Density of the rock is 25g/5ml=5 g/ml
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
Materials such as beakers, measuring cups, volumetric flasks, and syringes can be used as substitutes for a graduated cylinder when measuring liquids. It's important to note that while these alternatives can be used, they may not provide the same level of accuracy as a graduated cylinder.
You should read a graduated cylinder at eye level. See the related link for rules regarding menisci.
A graduated cylinder has a constant diameter and a printed scale on its side that indicates volume inside the graduated cylinder for any given liquid level. A flask has none of these advantages.
When measuring with a graduated cylinder, you pour the liquid into the cylinder to a precise level. Read the measurement at the bottom of the meniscus, which is the curved surface of the liquid. Be sure to read the measurement at eye level for accuracy.
To find the density of a grape, you must fill a graduated cylinder to exactly 200 mililiters. Then drop the grape in, wait till the water settles. Then subtract the new water level from 200 milliliters and then you have your answer.
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
Density = mass/volume. You may have trouble finding density because the object may be irregular. To find volume of an irregular shaped object, you can apply calculus to calculate volume.~ Or you can use water displacement, You take a graduated cylinder and fill it full of water, record the amount, then place said object in the graduated cylinder and record the water level, subtract the original from the last and convert it to cc(hint hint: CC=ML) to get the volume, weigh it in order to get the mass and viola!

The volume of the object placed in the water is 23 ml. This can be calculated by subtracting the initial water level (30 ml) from the final water level (53 ml).
