A piece of metal with a mass of 167 g is placed in a 50 mL graduated cylinder The water level rises from 20 mL to 36 mL What is the density of the metal?

Density = mass/volume = 167g/ (volume displaced) = 167g / (36mL - 20mL) = 167g/16mL = 10.4g/mL. Density is usually recorded in g/cm3 which is the same as g/mL so the density is 10.4g/cc.
Also, to be extra correct, the answer should be rounded to 10g/cc because 16mL only has 2 significant figures so that is the number you report in your final answer.

A piece of metal with a mass of 163 g is placed in a 50 mL graduated cylinder The water level rises from 20 mL to 36 mL What is the density of the metal?
The 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.)
How could you find the volume of a small rock using only a graduated cylinder and rock?
Note 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.
When reading the volume of fluid in a graduated cylinder the eye should be .?
Level with the bottom of the fluid's meniscus
How do you know that the rock in the figure with the graduated cylinder has a volume of 10 mL?
The level of the liquid in the cylinder rose by 10 mL when the rock was submerged in the liquid.
How is the mass of a rock measured?
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.
What will the water level be when all four marbles are in the graduated cylinder?
Graduated Cylinder - Marbles

What is the density of a chunk of silicon weighing 8.763 was placed in a graduated cylinder containing 25.00 of water the water level in the cylinder rose to 28.76?
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.
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
A stone is placed on a graduated cylinder which has been filled to the 35-ml mark The level rises to 42 ml What is the volume of the stone?
The Volume of the rock is 7-2=5 ML then the Density of the rock is 25g/5ml=5 g/ml
What materials can be used as substitutes of graduated cylinder?
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.
When reading a graduated cylinder you should have it at?
You should read a graduated cylinder at eye level. See the related link for rules regarding menisci.
Why is a graduated cylinder more accurate than a flask?
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 liquid into a what?
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.
How do you find the density of a grape?
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.
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
How do you find the density of an irregularly shaped object?
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! Density on a platter!~snooki">~ 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!
