41. Likewise the empirical formula for hydrogen peroxide,, is simply HO expressing the 1 : 1 ratio of component elements. 42. For polymeric materials, such as minerals and many metal oxides, the empirical formula is normally given, e . g. 43. The empirical formula of TGS does not represent the molecular structure, which contains protonated glycine moieties and sulfate ions. 44. Traditionally this process involved lengthy and complex calculations in conjunction with a mixture of practical experience and empirical formula . 45. The empirical formula for benzene had been long known, but its highly unsaturated structure was a challenge to determine. 46. In 1832, French chemist Jean Baptiste Dumas and German chemist Justus von Liebig determined the empirical formula for acetone. 47. The phosphate ion is a polyatomic ion with the empirical formula and a molar mass of 94.97 g / mol. 48. He used an empirical formula which assumed 33 % of the water flow would be lost to evaporation and seepage. 49. Analytical determination of the amounts of water and carbon dioxide produced from a known amount of sample gives the empirical formula . 50. The various metaphosphate ions ( which are usually long linear polymers ) have an empirical formula of and are found in many compounds.
