Answer:

11.688g

Explanation:

You use the equation #"moles"="mass"/"molar mass"#

You want mass so you isolate the mass, which results in #"mass"="moles"*"molar mass"#

You substitute the molar mass of NaCl which can be found in the periodic table (58.44 #gmol^-1#)

#"mass"=0.2*58.44#
mass = 11.688g
