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.
Platinum has a density of 21 g/cm3. A platinum ring is placed in a graduated cylinder that contains water. The water level rises from 5.0 mL to 5.3 mL when the ring is added. What is the mass of the ring?
6.3

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?
Mass of silicon = 8.763 (grams? tons?) Volume of silicon = 28.76 - 25.00 (cc? cubic meters?) = ..... Density = Mass of silicon divided by Volume of silicon. = ....... gms/cc? tons/cubic-metre?
A total of 32.95 grams of mossy zinc was placed into a graduated cylinder containing 50.0 mL of water The water level rose to 54.6 mL Determine the density of the zinc?
32.95 / (54.6 - 50.0 ) = 7.163 g/cm3 = 7163 kg.m3
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

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.
