Understanding Moles and Avogadro's Number

* Mole (mol): A unit of measurement for the amount of a substance. One mole contains 6.022 x 10^23 particles (atoms, molecules, etc.). This number is called Avogadro's number.

Calculation

1. Calculate the number of atoms in 10 moles of carbon:

* 10 moles C * (6.022 x 10^23 atoms/mole) = 6.022 x 10^24 atoms of carbon

2. Calculate the number of atoms in 10 moles of calcium:

* 10 moles Ca * (6.022 x 10^23 atoms/mole) = 6.022 x 10^24 atoms of calcium

Conclusion

Both 10 moles of carbon and 10 moles of calcium have the same number of atoms (6.022 x 10^24 atoms).
