How are atomic emission spectra used to identify elements?
As the atom emits photons at precise frequencies it creates a similar
atomic emission spectra to other atoms within its group.
Atoms absorb photons and emit energy at definitive frequencies creating a
universal atomic emission spectra common to all atoms.
When the atom absorbs photons, energy can only be emitted at specific
frequencies creating a characteristic atomic emission spectra.
The atom absorbs photons and emits a continuous spectrum of energy but
only certain frequencies can be detected creating the spectra.

37.7 x 101cm^3

Explanation: The easiest way to remember is that you move the decimal the unit difference x the power. So in this case, 1 x 3. So the answer is 3.77E1 or 37.7 cm^3. Another example would be if you were converting the same to m^3 instead. mm to cm to dm to m, so it is a decimal move of 3 x 3 or 9, or 3.77E-5. Hope this helps.
