12. Convert 600 mg to grams. Show your work.
nadya68 [22]

Answer:

600 milligrams=0.6 grams

Explanation:

1 milligram=0.001 grams and 1 gram= 1000 milligrams

So, to convert milligrams to grams, multiply the mg value by 0.001 or divide by 1,000.

Example:

If you want to know how many grams 300 mg is, you would divide 300 by 1,000, which would get you 0.3 grams.

Explain how understanding of atomic emission spectrum led to development of the atomic theory
Anon25 [30]

Max Planck presented a theoretical explanation of the spectrum of radiation emitted by an object that glows when heated. He argued that the walls of a glowing solid could be imagined to contain a series of resonators that oscillated at different frequencies. These resonators gain energy in the form of heat from the walls of the object and lose energy in the form of electromagnetic radiation. The energy of these resonators at any moment is proportional to the frequency with which they oscillate.

To fit the observed spectrum, Planck had to assume that the energy of these oscillators could take on only a limited number of values. In other words, the spectrum of energies for these oscillators was no longer continuous. Because the number of values of the energy of these oscillators is limited, they are theoretically "countable." The energy of the oscillators in this system is therefore said to be quantized. Planck introduced the notion of quantization to explain how light was emitted.
