## How many moles are in a gram of copper?

The relation between molecular (formula) mass and molar mass Page 4 4 • To obtain one mole of copper atoms (6.02 x 1023 atoms), weigh out 63.55 g copper. The molar mass (M) of a substance is the mass of one mole of entities (atoms, molecules, or formula units) of the substance.

## How much copper is in a mole?

Explanation: From your Periodic Table we learn that one mole of copper, 6.022×1023 individual copper atoms have a mass of 63.55⋅g . And thus we use the MASS of a chemical sample to calculate the NUMBER of atoms and molecules.
