The symmetry energy density derivative coefficient in the symmetry energy of the equation of state of the nuclear matter must affect masses and radii of unstable nuclei. In the previous work we have investigated a sensitivity of to the nuclear radii and applied for the possibility of existence of the "pasta" nuclei in the neutron-star crust. In this work we examine a sensitivity of to the nuclear masses in the light nuclidic region up to nickel isotopes. We extract a macroscopic feature from the nuclear masses based on the Yamada-Matsumoto-type systematics, and try to give a value of determined by the experimental masses. We will discuss an ambiguity of in this presentation.
