Noun
a chemical formula showing the ratio of elements in a compound rather than the total number of atoms
Source: WordNetA compound's empirical formula is a very simple type of chemical formula. Source: Internet
Contrary to popular belief, the 2:1 ratio observed in the DC electrolysis of acidified water does not prove that the empirical formula of water is H 2 O unless certain assumptions are made about the molecular formulae of hydrogen and oxygen themselves. Source: Internet
Berthelot's empirical formula for acetylene (C 4 H 2 ), as well as the alternative name "quadricarbure d'hydrogène" (hydrogen quadricarbide) were incorrect because chemists at that time used the wrong atomic mass for carbon (6 instead of 12). Source: Internet
Examples * Glucose (replace), ribose (replace), acetic acid (replace), and formaldehyde (replace) all have different molecular formulas but the same empirical formula: replace. Source: Internet
An example of the difference is the empirical formula for glucose, which is CH 2 O (ratio 1:2:1), while its molecular formula is C 6 H 12 O 6 (number of atoms 6:12:6). Source: Internet
A variety of compounds of empirical formula AlR 3 and AlR 1.5 Cl 1.5 exist. Source: Internet
