Use this information to calculate Avogadro’s number. (Atomic mass of Fe = 56.0 u) a = 286.65 pm = 286.65 x 10-10 cm. Density (Ï) = 7.874 g cm-3. At mass of Fe = 56

Fe(NO2)2 is easy to decompose. Example Reactions: How many Fe atoms are in 95.8 g of Fe? The number of atoms cannot be calculated directly from the mass. We must first determine the number of moles of Fe atoms in the sample and then use Avogadro’s number. PLAN: mass (g) of Fe amount (mol) of Fe atoms of Fe divide by M of Fe (55.85 g/mol) multiply by 6.022x1023 atoms/mo Mass Number. The mass number (\(A\)) of an atom is the total number of protons and neutrons in its nucleus.
