Answer 2

Luminous intensity and  amount of substance

Explanation:

Luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd).

The amount of substance in a given sample of matter is the number of discrete atomic-scale particles in it divided by the Avogadro constant. The particles or entities may be molecules, atoms, ions, electrons, or other, depending on the context. The mole (mol) is that amount of substance that contains the same number of elementary entities as there are atoms in 12g of carbon 12.
