You need an approx. #120*g# mass.

#"Concentration"="Moles of solute"/"Volume of solution (L)"#,

and thus:

#"mass of solute"="concentration"xx"volume"xx"molar mass NaOH"#.

Given that #"Concentration"= 3*mol*L^-1#, in a #1*L# volume, there are #3*mol*L^-1xx1*Lxx40.0*g*mol^-1=??g# #"NaOH"#.

What is the #pH# of this solution?
