A mass of 4.0*g "sodium hydroxide" is required............

Explanation:

"Concentration" = "Moles of solute"/"Volume of solution"

Here, "concentration" = 1.0*mol*L^-1, "volume" = 100*mL.

And thus "moles of solute" = "Concentration "xx" Volume"

=1*mol*L^-1xx100xx10^-3L=0.100*mol.

And thus "mass of solute" = "number of moles "xx" molar mass"

=0.100*molxx40.0*g*mol^-1=??*g.
