$20.3\ g$ $Ne$ has the greater number of atoms.

Work Step by Step

Molar mass of $Ne$ $\approx 20.18\ g/mol$. So: 1 mol $Ne$ $\approx$ 20.18\ g Since we are comparing the number of moles for the same specie (Ne), a greater mass means a greater number of atoms. So: $20.3g > 20.18g$ Thus: $20.3\ g$ $Ne$ has more atoms than $1$ mol $Ne$
