Well there is a an easy experiment you deserve to do come answer your very own question. You can probably “ask the internet via google”, yet why perform that?Instead execute an experiment.
You are watching: What is the mass of an egg
fact is the ultimate arbiter! and an experiment permits us to identify reality.
This is crucial lesson. scientific research is the “belief in the possible ignorance that experts”. What I median is not that one “expert” have to be ignored… in practically all cases TRUE experts are to be trusted, such as the meteorologists who carry out weather forecasts. However, IN THE END, experiment is the can be fried arbiter of the TRUTH.
So thickness is the mass/volume of an object. an initial you will call for a simple kitchen scale. The very first thing to execute is to achieve the mass of the egg. I have a small kitchen scale and I can measure the mass in grams or ounces. If you do measure in ounces convert TO GRAMS.
Then to measure up the volume you deserve to do this: fill a broad cup, speak a file or plastic cup, cup roughly half way v water. Note the water line with a sharpie. Then very closely place the egg in NO SPLASH!!… and also mark the brand-new height that the water line. The displaced water is the volume of the egg. you can carefully pour water out till the egg add to water heat returns come the very first (pre egg in the cup) level. So now you deserve to take the water you removed and also determine that mass. Since the thickness of water is 1 g/ cubic centimeter you deserve to take that mass of water to be the VOLUME that the egg in cubic centimeters.
Now you have the density= massive of egg/ volume the egg.
Question: walk the thickness of egg change if you first hard cook it?
Answer: NO… neglecting any kind of TINY, TINY alters in volume and also assuming no leakage of fixed from within the egg to outside (it would certainly be supervisor minor), the mass and the volume has actually not changed! The thickness is the same.
HOWEVER, it is straightforward to determine if an egg is difficult boiled or not!!! through experiment!! The density does no change, so that is no test.
What changes between a fresh egg and a hard-boiled egg??
The circulation OF massive changes. The plot of boiling makes the minute of inertia decrease. This is because when egg white is converted to difficult egg white the thickness increases much less than once the egg yolk experience the liquid to heavy conversion. This means that if friend spin by THE SAME pressure a boiled egg and a non-fresh one, for the same amount of hand spin, the boiled egg will certainly spin faster. This is the principle of the conservation the angular momentum. The mass distribution has adjusted such that more of the fixed of the egg is CLOSER come the spin axis or facility of the egg.
So over there you have it. use your creative mind come measure things experimentally and make monitorings (spin the eggs) and also then administer an explanation regular with Nature. This is the hallmark that a scientist; yet the an approach can be used to deal with many, countless other issues as well.
According come a ahead civicpride-kusatsu.net science Line inquiry (“How much salt execute we require in water to make an egg float?”), the average density of one egg is 1.031 grams per cubic centimeter. However, every egg is different, and there will certainly be little variations in density.
For comparison, in ~ room temperature (20oC or 68oF), water has actually a thickness of 0.998 grams per cubic centimeter (Source: CRC Handbook of Chemistry and Physics). For this reason most eggs will certainly sink in water, together they are (slightly) much more dense.
BUT, as eggs gain old, a little bit of water evaporates out with the shell and is changed by air. Since air is much less thick than water, this process lowers the density of the egg. Eventually, the egg thickness will drop sufficient that the egg have the right to float in water. So, if you want to inspect how new an egg is, you have the right to test whether it floats or sinks in water. If the is old sufficient to float, you probably shouldn’t eat it!
Interesting question, and let’s begin with the basics: what is density? thickness is a physical property of an object (e.g. The egg), and also is defined as the massive of the object, regularly given in grams, (how lot egg is there) divided by the volume, frequently given in cm3 or milliliters, (how much an are the egg takes up). Mathematically, this is offered as D = m / V, where “D” is density, “m” is mass, and “V” is volume. Therefore, if you recognize the fixed of things and that volume, friend can easily calculate its density.
now with the basics laid, let’s look at your question, and also in particular, the use of the word “egg”. because that our purposes, let united state assume it means hen egg (those you commonly consume for a hearty breakfast), yet the procedure to recognize the density for any other egg would certainly be the same. Because that a quick measure, try putting an egg in a cup the water; it will sink, and indicate that the thickness of the egg is greater than water (density of water is 1 gram/milliliter) as objects more dense than water will sink in water. As for a an ext rigorous means to determine the exact density of the egg, place the egg in water, and then include salt come the water until the egg begins to float, especially the leaf of the egg is even with the surface of the water, and this is when the water v salt has actually the same density as the egg. Finally, sweet the water v salt ~ above a scale to obtain the mass, recognize the volume by using cooking ware that deserve to measure in milliliters, and then division those numbers, and you have actually arrived in ~ the thickness of your breakfast egg.
I do the efforts to do the experiment, yet it didn"t work very well. My chicken egg weighed 2.0 ounces, which is 56 grams. I put it in a measuring cup and also filled to cup to 250 milliliters
With better measurements, an egg is just a tiny little bit denser than water.

That renders sense, due to the fact that the egg barely sink in water.
