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.
Step 1: Find the atomic mass of each element in the molecule. The first step to finding mass percent is to find the atomic mass of each element in the molecule. K 3 Fe(CN) 6 is made up of potassium (K), iron (Fe), carbon (C) and nitrogen (N).Using the periodic table : Atomic mass of K: 39.10 g/mol.ach element's contribution is expressed as a percentage of the whole. This step by step tutorial will show the method to determine the mass percent composition of a molecule. Example: Calculate the mass percent composition of each element in a potassium ferricyanide, K 3 Fe(CN) 6 molecule.
