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.
Simply add each mass contribution together to find the total. Molecular mass of K3Fe(CN)6 = 117.30 g/mol + 55.85 g/mol + 72.06 g/mol + 84.06 g/mol. Molecular mass of K3Fe(CN)6 = 329.27 g/mol. Step 4: Find the mass percent composition of each element. To find the mass percent composition of an element, divide the mass contribution of the element by the total molecular mass.
