6.023multiply 10 to the power 23 multiply 8 upon 32​

Answer 1

Avagadro’s Number.

Basically, dealing with the weights of atoms and molecules individually is next to impossible. But, dealing with the weight of a LOT of atoms is easy!

So, they started by defining something called atomic mass. The unit of atomic mass is defined as that of a proton. This means that every element and molecule has an average atomic mass.

Then they decided on a more useful measurement—the gram. Grams are easily measured in the lab.

They then calculated how many atoms/molecules they needed so that if the atom has atomic mass X, that the amount of substance they have weighs X grams.

That number is Avagadro’s Number, 6.023 × 10^23. That amount is also called one mole of substance, and it's very useful in chemistry when trying to determine how much stuff you have.
