450 ml of 0.8 M NaOH contains 0.36 moles NaOH (0.8 Moles / liter x 0.450 liter)

Na OH weighs 23 + 16 + 1 = 40 g / mole

0.36 moles x 40 g / mole = 14.4 grams

do your own homework

work out grams>moles in NAOH (sodium hydroxide)

then moles per DMcubed

convert DM3 to ml and do the rest of the math

(0.8moles/L) (0.450L) = 0.36 moles X M.W= g NaOH
M.W= 40 g/moles
