For the answer to the question above, the correct answer is 4.000 sample of sodium hydroxide (NaOH) has a mass of 160.0 g which is equal to 4 moles of NaOH. TO calculate this, we use the relation of the molar mass given.

I'll show my solutions below.

160.0 g NaOh (1 mol NaOH / 40.0 g NaOH) = 4.000 mol NaOH
