How many atoms are in 4.3 moles of copper atoms?

Answer :

Final answer:

There are approximately 2.59 x 10²⁴ copper atoms in 4.3 moles of copper. This is computed by multiplying the number of moles (4.3) by Avogadro's number (6.022 x 10²³ atoms/mole).

Explanation:

The question is asking how many atoms are in 4.3 moles of copper atoms. In chemistry, the concept of Avogadro's number, which is approximately 6.022 x 10²³, is used to represent the number of entities (usually atoms or molecules) in one mole of substance. In this case, to find the number of atoms in a certain number of moles, you can simply multiply the number of moles by Avogadro's number.

So in this case, you would calculate:

4.3 moles x 6.022 x 10²³ atoms/mole = 2.59 x 10²⁴ atoms

This means there are approximately 2.59 x 10²⁴ atoms in 4.3 moles of copper.
