Finding the number of atoms in 0.500 mol of Argon

[canadiangirl3]

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?

 

[Borek]

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?

 

[Feldoh]

That is correct!

For future reference that constant is Avogadro's number.
