Which scientist’s law about the ratios of masses of elements in a compound did john dalton’s work on the atomic structure to explain?
democritus
j. j. thomson
ernest rutherford
joseph proust

I believe the correct answer from the choices listed above is the last option It is Joseph Proust's law about the ratios of masses of elements in a compound did John Dalton’s work on the atomic structure help to explain. Dalton's law of multiple proportions is part of the basis for modern atomic theory, along with Joseph Proust's law of definite composition. Hope this answers the question.
