Radio Terms and Abbreviations. The nomenclature of the radio hobby can be bewildering! The following is a list of some of the more widely used (and confused!) terms and abbreviations found in ham radio, shortwave radio, and scanner monitoring.
3 The theoretical value of the % oxygen in potassium chlorate is calculated from the formula KClO 3 with a molar mass = 122.6 g/mol. Frequently it is interesting â and instructive-to determine the percent error of an experimental. determination.ou will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO. 3) is heated, it undergoes chemical decomposition. Oxygen gas (O 2) is given off and potassium chloride (KCl) remains as the residue.
Element X = 20.0 g X / 80.0 g total x 100% = .250 or 25.0 %. Element Y = 60.0 g Y / 80.0 g total x 100 % = .750 or 75.0 %. Here is a video which discusses how to calculate percent composition from experimental data for a reaction of iron and oxygen which produces an iron oxide compound.
