The mass of eight moles of sodium chloride is #~~500"g"#.


Multiply the given moles of sodium chloride times the molar mass of sodium chloride.

Molar mass of NaCl is #"58.44g/mol"#. https://www.ncbi.nlm.nih.gov/pccompound?term=NaCl

#8cancel"mol NaCl"xx(58.44"g NaCl")/(1cancel"mol NaCl")="467.52 g NaCl"="500 g NaCl"# to one significant figure.
