Homework Help: Finding the number of atoms in 0.500 mol of Argon

  1. Mar 17, 2009 #1
    Question: How many atoms are there in 0.500 mol of Argon?

    No relevant equations

    do you take atomic molar mass (39.95) divided by 0.500 mol?

    Do you know a constant that relates moles to atoms?

    Remember: mole is just an overgown dozen.

    Well, I think 6.02 x 10^23 represents the number of atoms in a mol, right? so 0.500 of a mol x 6.02 x 10^23 = 3.01 x 10^23. Is that the correct answer?

    That is correct!

    For future reference that constant is Avogadro's number.
