The same way you measure other everyday objects. One way to do this is by weighing them. This is an indirect measurement, but on Earth, you can consider weight to be proportional to mass.
Immerse it in water and measure the displacement. Then calculate the mass of the amount of water displaced.
a gradute is used to measure mass
You can't measure mass in meters. Meters is a measure of length, not mass
Mass
You need to have the volume and the mass to calculate the density
The vinegar isn't absorbed by the egg.
Grams would be best units to use for the mass of an egg. All the three friends have given the right one. Weight and mass are different. Weight is a force where as mass is just quantity of matter.
Gravitational energy is U = mgh. Therefore, you need the egg's mass and the height at which it will be dropped. g=9.8
a grass hopper's egg mass is called a "egg pad"
As the egg decomposes, the mass of the egg is reduced. This is because the egg shell is porous and water vapor and gases can escape over time, reducing the mass of the egg. If the mass of the egg is less than the mass of the volume of water displaced by the egg, it will float.
Egg float in water because the mass of the water is less than the mass of the egg.
It depends on whether you wish to measure its: mass, volume, age, temperature or some other characteristic. It would have helped if the question was a bit more specific!
the instrument used to measure the radius of an egg is episometer
Mass is the measure of matter in an objevt

Scales either measure mass, or weight - but they are callibrated to show mass (for example, kilograms).
a gradute is used to measure mass
You measure mass in kilograms,grams,tonnes,short tons,pounds and ounces
