3. Compute Mass of Each Element Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in (NH4)2Fe(SO4)2.6H2O: Molar Mass (g/mol) N(Nitrogen)2 × 14.0067 = 28.0134 ...
2. Find Atomic Mass of Each Element Next, using theperiodic table, find the atomic mass in g/mol of each element (the molar mass of an element is equal to its atomic mass): Molar Mass (g/mol) Fe(Iron)55.845 H(Hydrogen)1.00794 ...
Why use molar enthalpies of formation Klicke auf die Karteikarte, um sie umzudrehen. 👆 Sometimes you are provided with neither calorimetric data nor a series of reactions to manipulate. In these cases, you must use the "molar enthalpies of formation" method to make enthalpy predictions.It...
