Question

Eli5 how one mole of any element or compound could have same no. of atoms or molecules??

In: Chemistry

Answer 1

That’s the definition of a mole. A mole is a set number of atoms (more specifically, 6.022×10^23).

Think about one dozen (12). A dozen doughnuts is 12 doughnuts and a dozen eggs is twelve eggs. They have different masses, weights, and volumes, etc. but a dozen is still 12.
