Understanding Avogadro's Number and the Role of Carbon-12 in the Mole Concept

[Larrytsai]

Can someone explain to me what 12 grams of carbon 12 is and how to use avogrados number?

I think your question should be a little more specific. 12 grams of Carbon 12 is just that. . . it's 12 grams of Carbon 12.

Now there are probably many uses for Avro's number. Do you have an example?

12 grams of Carbon-12 is a lot of things.. and for one as Saladsamurai said, it is 12 grams of Carbon-12.

From, your question and the post's title, one other thing that might be relevant to you is that the no. of atoms in 12 grams of Carbon-12 atom is known as the Avagadro's Number, or N_A and is equal to 6.023 \times 10^{23}. That much of anything is said to be 1 mole of anything.

The 'mole' is something like a dozen or a gross. As 12 makes a dozen, 6.023 \times 10^{23} makes a mole. So, as u have a dozen of apples, u have a mole of atoms.

EDIT: Be a little more specific when asking questions in the homework forum. Vague and one-line questions give no clue as to what you mean. You don't buy this service, you ask for help. No hard feelings.
