Mass:
Mass is quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force.
'Mass' is a property of physical objects which, roughly speaking, measure the amount of matter contained in an object. It is a central concept of classical mechanics and related subjects. In the SI system of measurement, mass is measured in kilograms.
b)the mass of an average galaxy.
This is a real poser for us; nobody seems to have an answer more accurate than 'a lot.' So could you give us the best estimate we have today of the number of in the universe? and the average mass of a galaxy?

Examples: Mass is the property of a body that is a measure of its inertia (lacking the power to move). Mass is commonly taken as a measure of the amount of material it contains and causes it to have weight within Earth's gravity.

CALCULATING THE MASS OF THE EARTH
1. F = GmM/r2 = ma, where F is the gravitational force, G is the gravitational constant, M is the mass of the Earth, r is the radius of the Earth, and m is the mass of another object (near the surface of the Earth).
(Image credit: NASA/CXC/SAO.) These stars live comparatively faster and more dramatic lives than lower mass stars.
The Earth's fossil record is peppered with mass extinction events - when a large number of species died out in a very short period of time. The most well known is the event that caused the death of the dinosaurs 65 million years ago.
