How many atoms in 8 grams of copper?

Answer 1

Actually, it depends very much on how big your piece of copper is, but in just a small coin made of copper, you can actually find many billions or even trillions of atoms of copper.

Extra fact:

Atoms of elements are actually so small that their atomic radii are measured in pico meters (1pm=1x10-12m)

Answer 2

Find the moles by taking the 8 grams and dividing by the molecular weight of Cu.

Then multiply the moles by Na (6.02*10^23).

Answer 3

One gram of copper is roughly 9.48 *1021 atoms. This is by 1g = .0157 mols * 6.02*1023 atoms/mol.

Answer 4

28.0 grams copper (1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu)

= 2.65 X 1023 atoms of copper

======================

Answer 5

1 g of copper is equal to 9,4768.10e21 atoms.

Answer 6

1 g copper = 0,09476.1023 atoms

Answer 7

2.84 X 10^23 atoms Cu

Answer 8

8.44e-22 g
