Convert the given density in mg/dL into a quantity with unit of g/L. This is shown below,
(200 mg / dL) x (10 dL / L) x (1 g / 1000 mg) = 2 g/L
Multiplying this quantity with the volume given, 5L, gives an answer of 10g.

<u>Answer:</u> The mass of NaOH is 40 g
<u>Explanation:</u>
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:
.....(1)
Given values:
Molarity of NaOH = 1 M
Molar mass of NaOH = 40 g/mol
Volume of the solution = (Conversion factor: )
Putting values in equation 1, we get:
Hence, the mass of NaOH is 40 g
