First, you must understand that M = moles per liter. This allows us to determine how many moles there are in any volume since we have the ratio.
Simply convert ml of solution to L, then use your M, molarity, to convert to moles of NaOH.
.65ml x (1L / 1000ml) x (2.25mol / 1L) = .00146mol NaOH
But you're not done! It asks for the mass! So, convert moles of NaOH to grams using molar mass.
.00146mol x (39.9g / 1mol) = .058g NaOH
