Does the value of mole change with the change of elements?

Thr value of mole is same or you can say constant, just like a dozen contains 12 of anything, a mole contains [math]6.022 × 10^23[/math] no. of particles which can be atoms, molecules, ions. read more

Taken to atoms, this meant that at one point in history it was defined to take the amount that weighs $z~\mathrm{g}$ of element $\ce{Y}$ as a value for ‘one count’ — one mole. That definition was changed and currently, $12~\mathrm{g}$ of $\ce{^12C}$ atoms is the number of atoms in a mole. read more

The atomic weight, molecular weight, or formula weight of one mole of the fundamental units (atoms, molecules, or groups of atoms that correspond to the formula of a pure substance) is the ratio of its mass to 1/12 the mass of one mole of C 12 atoms, and being a ratio, is dimensionless. read more
