9. If black body radiation is treated classically (without quantization) the result is (A) Too much light at low frequencies
(C) Too much light at high frequencies
(B) A perfect match to quantum theory
(D) Correct only at very low temperatures

What is the maximum number of electrons that an atomic orbital can contain?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

What is the energy in joules of a mole of photons associated with visible light of wavelength 486 nm?
