Well, you can only have either sodium chloride or lithium chloride. #"NaLiCl"# doesn't exist.

The percent by mass is:

#%"w/w" = "mass solute"/"mass solute + solvent" xx 100%#

And so,

#color(blue)("Percent by mass") = "4.92 g solute"/("4.92 g solute" + "347 g water solvent") xx 100%#

#= color(blue)(1.40% "w/w")#
