A $\text{mole}$ is simply a NUMBER......
A $\text{gram atom}$ is a bit of an old-fashioned term, that refers to the mass of $\text{Avogadro's number}$ of $\text{atoms}$............i.e. a gram atom of carbon is $12 \cdot g$, of oxygen is $16 \cdot g$, of hydrogen is $1 \cdot g$.
And each of these $\text{gram atoms}$ specifies precisely $\text{Avogadro's Number}$ of atoms, i.e. $6.022 \times {10}^{23} \cdot m o {l}^{-} 1$.
