Answer: Yes the absorb in the visible range.
Explanation:
The relationship between wavelength and energy of the wave follows the equation:
where,
= energy of the wave = 182 kJ/mol = 182000 J/mol
N = avogadro's number =
h = plank constant =
c = speed of light =
= wavelength of the wave = ?
Putting all the values:

The wavelength range for visible rays is 400 nm to 750 nm, thus the complex absorb in the visible range.

Explanation:
A dibasic acid is an acid that has two oxygen ions to donate to a base in an
acid-base reaction.
Therefore, a dibasic molecule has two replaceable hydrogen atoms.
The molar mass of salt (NaCl) is 22.99+35.45 = 58.44 g/mol. If we have 0.18 mg of salt, this is equivalent to 0.00308 mmol NaCl, or 3.1E-6 mol NaCl. By definition, 1 mole contains 6.02E23 formula units, so multiplying this by the number of moles gives the answer, which is: 1.9E18 formula units.
