His views, which were adopted and put on a frm experimental ±oundation in the early 19th century by the British chemist [and devout Christian] John Dalton, ±orm the basis ±or all modern chemistry”( The Great Physicists from Galileo to Einstein by George Gamow, p. 209). A colleague o± Dalton’s, J. L. Proust, is credited with being the frst to describe the Law o± Constant Composition, which states that ±or every pure compound the mass ratios o± its constituent elements are constant. I± the mass ratio is constant, then the ratio o± elements is also constant, and a chemical ±ormula indicating the relative propor- tions o± the elements in a molecule (rather than the actual number o± atoms) is called an emprical formula . Using glucose as an example, its molecular ±ormula is C 6 H 12 O 6 , while its empirical ±ormula is CH
