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.)
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.
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.
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.

Graduated Cylinder - Marbles
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?
32.95 / (54.6 - 50.0 ) = 7.163 g/cm3 = 7163 kg.m3
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
The Volume of the rock is 7-2=5 ML then the Density of the rock is 25g/5ml=5 g/ml

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.
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.
