Answer:
There are 2 atoms in NaCl. This is because there is 1 atom of Na (sodium) and 1 atom of Cl (chlorine) in each NaCl molecule. Elements by themselves do not have a "number of atoms"- if you're talking about the atomic number, it's the number of protons (or electrons in a neutral atom) of an element.

The question is incomplete, here is the complete question:
A murexide soution has a concentration of and an absorbance of 1.850 and the path length is 1 cm. What is the molar absorptivity of the solution?
<u>Answer:</u> The molar absorptivity coefficient is
<u>Explanation:</u>
To calculate the molar absorptivity coefficient, we use the equation given by Beer-Lambert law, which is:
where,
A = absorbance = 1.850
= molar absorptivity coefficient = ?
C = concentration of the solution =
l = path length = 1 cm
Putting values in above equation, we get:
Hence, the molar absorptivity coefficient is
Answer:
The top layer was the organic layer.
9-fluorenone was most soluble in the organic layer.
Deprotonated chloroanilic acid was most soluble in the aqueous layer.
The bottom layer was the aqueous layer.
The organic layer was a yellow colored solution.
The aqueous layer turned into a pink colored solution.
