Answer:
a) Absorbance
b) The absorb light most strongly in 580nm
Explanation:
Beer-Lambert law relates concentration with light absorbance. The more concentrated solution are the more molecules and the most absorbance.
Wavelenght depends of composition of solution and doesn't change with different concentrations of the same solution.
Transmittance is inversely proportional to absorbance. Thus, the more concentrated solution the less transmittance.
Colored compounds are absorb energy of visible radiation. The colour that we see is a result of the absortion of complimentary colour (Colour wheel). Thus, a blue-green solution absorb energy of ≈600 nm. Thus, the absorb light most strongly in 580nm.

The four quantum numbers for an atom refer to the state of the valence or outermost electron. For a potassium atom, the electron configuration is 1s22s22p63s23p64s1 , which means that n=4
Answer:
mass number
Explanation:
The sum of the protons and neutrons in an atom equals the mass number of such an atom.
- Mass number is the mass of an atom.
- The mass of an atom is concentrated in the nucleus
- The particles in the nucleus are the protons and neutrons.
So;
Mass number = number of protons + number of neutrons.
