So in chemistry, what is the meaning of the term mole? and also why is this important to apply the mode concept in chemistry? so first of all, most, one mole is corresponding to 6 .02 times 10 to power 23 of something.
00:17
So it's a very similar concept to have, we have 1 ,000 of donuts, so we have 12.
00:23
So instead of using counting individual 1, 2, 3, 4, individual atom, molecule, or, or ions, we're going to use more we have 6 .02 times 10 to the power of 23.
00:37
So the reason that we are using the rv -goucult number of the number of most in chemistry is that, in chemistry, we always handle a really large number of atom or molecule or reactant.
00:50
So the number will very large.
00:52
It can go up to 10 to the 40, 10 to the 50.
00:57
It depends how many substance you use.
01:00
So if we are going to use, a unit for example the mode concept we will make our correlation easier because we are going to handle a relative smaller number just relative smaller number and we can handle it so we'll make our calculation to be easier okay so second one is important because in chemistry for example we have a chemical reaction of the a plus b to c from here if we want to do stoichiometry you want to do to look at the relationship, how many substance we need to use the react and also how many substance is going to produce.

From our chemical reaction, we know that one molecule a, we have with one molecule of b...
