The molecular weight of sodium hydroxide is 40. Therefore 0.150 moles would be 40 x 0.15 = 6g.
avagadro number
0,15 moles NaOH contain 6 g.
The atomic mass of sodium, Na is 23.0 Amount of sodium = mass of sample / atomic mass = 120/23.0 = 5.22mol

The iron(III) hydroxide is not soluble in water and doesn't react with sodium chloride.
The molecular weight of sodium hydroxide is 40. Therefore 0.150 moles would be 40 x 0.15 = 6g.
98g of phosphoric acid require 120g of sodium hydroxide to produce sodium phosphate so 150g phosphoric acid will require = 120/98x150= 183.67g sodium hydroxide.
