How many copper atoms are in a pure copper statue with a mass of 198 kg?

So in the periodic table, the atomic mass of one copper is 64.546.

One mole is 6.022x10^23 atoms.

You can use both of these to find the number of atoms.

The formula to find the amount of moles of something is "moles = grams / atomic mass"

103 kg --> 103,000 g.

103,000 divided by 63.546 = around 1620.873 moles.

All you need to do is multiply 1620.873 to 6.022x10^23 and you get the number of atoms in copper!

Ithink is d. physical property

Fine out you self hx
