Clarkson; Roger LeRoy Miller; Frank B. answered by DrBob222 January 8, 2016 (NH4)3PO4 = Nitrogen = 3 Hydrogen = 4x3 (12) Phosphorus = 1 Oxygen = 4 3+12+1+4=20 Gold = 196.97 g/mol Copper = 63.55 g/mol Molar Mass = Mass of 1 mol (6.02 x 10 23) of a substance (g/mol) Atomic Mass = Mass of 1 atom (amu) How are the terms "molar mass" and "atomic mass" the same? Examples are provided below. Treatment of an alkylbenzene with potassium permanganate results in oxidation to give the benzoic acid. Correct answer - What changes in color occur when bromine and kmno4 reacts with an alkene? With addition of heat and/or more concentrated KMnO4, the glycol can be further oxidized, cleaving the C-C bond. The mass of glucose can be calculated by multiplying the Answer: The molar mass of KMnO4 is calculated by adding the atomic masses of all the atoms in the compound: K (39 g/mol) + Mn (54 g/mol) + 4O (4x16 g/mol) = 158 g/mol. Since it is not my question I have nothing to lose :)), I'll let you into the hall of creditfame tonight.
