SUMMARY

The number of atoms in 0.500 mol of Argon is calculated using Avogadro's number, which is 6.02 x 1023 atoms per mole. By multiplying 0.500 mol by Avogadro's number, the result is 3.01 x 1023 atoms. This calculation confirms that the correct answer is indeed 3.01 x 1023 atoms. Understanding this relationship is essential for accurate conversions between moles and atoms.

PREREQUISITES
  • Understanding of Avogadro's number (6.02 x 1023)
  • Basic knowledge of moles and atomic mass

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?
 
Physics news on Phys.org
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.
