Witryna24 gru 2024 · The mole (abbreviated mol) is the SI measure of quantity of a “chemical entity,” such as atoms, electrons, or protons. It is defined as the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12. So, 1 mol contains 6.022×10 23 elementary entities of the substance. Witryna7 wrz 2024 · 3. Density is mass per unit volume. Find the mass and density of the atom (or molecule) and you can get the density. Atoms have nucleus and electrons, which give mass to it. Molecules have atoms which give mass to it. Obviously, they have some volume. So both of them can have densities.
