How many electrons are in 1.01 oz of a pure gold coin?

There are 6.83.10²⁴ electron particles in 1.01 oz of a pure gold coin

A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12

1 mole = 6.02.10²³ particles

While the number of moles can also be obtained by dividing the mass (in grams) with

So that in 1 mole of gold there are 6.02.10²³ gold atoms

In the gold atom itself (Gold atomic number = Au = 79) there are 79 electrons so the number of electron ions is: 79 x 6.02.10²³ particles = 4.75.10²⁵ electron particles

1.01 oz of a pure gold coin = 28,3495 grams

relative atomic mass Gold = 197 grams / mole

So that Gold mole = grams : relative atomic mass Gold

Gold mole = 28,3495 grams: 197 grams / mole

Gold mole = 0.1439

Then in 0.1439 gold mole, there are as many electron particles:

 0.1439 x4.75.10²⁵ = 6.83.10²⁴electron particles

Keywords: mole, Avogadro’s number, electron, gold

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
