Mass can be defined as a quantitative measure of an object's resistance to the change of its speed. . Scientifically speaking, mass IS different than weight, which is the measure of a planet’s gravitational force on an object. 23 . particles. . So a “mole” is a number, very similar to a dozen. . A dozen = 12 . A mole (mol) = 6.022 x 10. 23. It can be found in your reference packet on page one. Avogadro’s number = 6.022 x 10. 2. O. 3. ) . C/W. 23/09/2020. 3.2.1. Ar of Al = 27.

Calculate the molar mass of a . A Study in Scarlet. “In solving a problem of this sort, the grand thing is to be able to reason backward. This is a very useful accomplishment, and a very easy one, but people do not practice it much.”. Matter is made of different kinds of particles. . We count the number of particles of that substance. . Since there are a very large number of particles in any substance, we need to define a unit of measure:.
