## USAGE:

    valence_factor = gsw_valence_factor

## DESCRIPTION:

    This function returns the valence factor of sea salt of Reference
    Composition, 1.2452898.  This valence factor is exact, and follows from
    the definition of the Reference-Composition Salinity Scale 2008 of
    Millero et al. (2008).  The valence factor is the mole-weighted square
    of the charges, Z, of the ions comprising Reference Composition sea salt.

## OUTPUT:

    valence_factor  =  valence factor of sea salt of Reference Composition
                                                                 [ unitless ]

## EXAMPLE:

    valence_factor = gsw_valence_factor

    valence_factor =

      1.2452898
