    Almost. A mole is just a number, like a dozen. What if I said, "How many shoes are there in a dozen pairs of shoes?" This question is like that. How many hydrogen atoms are in a hydrogen molecule?

    Would there be 2 atoms in one molecule?

    Yes. Someone must have told you, it's impossible to guess.

    Yes. So how many hydrogen atoms are there in a mole of hydrogen molecules?

    Would that be 2 multiplied by Avogadro's constant?
