From the Periodic table, it can be determined that iron (Fe) has an atomic mass of 56 amu, oxygen (O) has an atomic mass of 16 amu, and hydrogen (H) has a mass of 1 amu. What would the atomic mass of Fe(OH)3

To determine the atomic mass of Fe(OH)3, we need to calculate the total mass of the iron atom, three oxygen atoms, and three hydrogen atoms in the compound.
Atomic mass of Fe = 56 amu
Atomic mass of O = 16 amu
Atomic mass of H = 1 amu
Fe(OH)3 contains one iron atom, three oxygen atoms, and three hydrogen atoms.
Mass of Fe(OH)3 = (56 amu) + (3 x 16 amu) + (3 x 1 amu)
= 56 amu + 48 amu + 3 amu
= 107 amu
Therefore, the atomic mass of Fe(OH)3 is 107 amu.
Answer: 107 amu
