#"6.634 g"#

Explanation:

#"Molarity" = "Moles of solute"/"Volume of solution (in litres)"#

#"0.284 M" = "n"/"0.4 L"#

#"n = 0.1136 mol"#

Solution contains #"0.01136 mol"# of #"NaCl"#

Formula mass of #"NaCl = 58.4 g/mol"#

Mass of #"NaCl"# in the solution#= 0.1136 cancel"mol" × 58.4\ "g"/cancel"mol" = "6.63424 g"#
