Copper Conversion and Atomic Mass

This video tutorial explains how to convert grams of copper to moles and then to atoms. It begins by introducing the concept of conversion using a mole map. The process involves dividing the given grams of copper by its atomic mass to find the moles. Then, the moles are multiplied by Avogadro's number to determine the number of atoms. The video concludes with a recap of these steps, emphasizing the use of atomic mass and Avogadro's number in conversions.
