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.
8.a) Find the # nitrogen and oxygen atoms present in a 23g sample of N2O4. MW N 2 O 4 = = 28g + 64g = 92 g/mole. # moles N 2 O 4 = = .25 mole. 1 mole N 2 O 4 2 moles N and 4 moles O. .25 moles N 2 O 4 2(.25) = .5 moles N and 4(.25) = 1 mole O. # N atoms = (.5 moles)(6 x 10 23 atoms/mole) = 3 x 10 23 N atoms. # O atoms = (1 mole)(6 x 10 23 atoms/mole) = 6 x 10 23 O atoms. 8.b) Find the #g of each atom. #g N = (.5 moles)(14 g/mole) = 7g N. #g O = (1 mole)(16 g/mole) = 16g O. 9.a) Find the # oxygen atoms in 284g of P 2 O 5.
