The mass of #"NiSO"_4# is 12.7 g.

Explanation:

Step 1. Calculate the mass of the solution

#"Mass of solution" = 200 color(red)(cancel(color(black)("mL solution"))) × "1.06 g solution"/(1 color(red)(cancel(color(black)("mL solution")))) = 212.0 "g solution"#

Step 2. Calculate the mass of #"NiSO"_4#

#"Mass of NiSO"_4 = 212.0 color(red)(cancel(color(black)("g solution"))) × "6.00 g NiSO"_4/(100 color(red)(cancel(color(black)("g solution")))) = "12.7 g NiSO"_4#
