The isotope shift of spectral lines refers to the shift in wavelengths (or frequencies) due to the different isotopic masses of given elements. Find the isotope shifts for each of the four visible Balmer series wavelengths for deuterium and tritium compared with hydrogen. (Enter each wavelength for each isotope to at least two decimal places. Enter your answers in nm.)

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.
