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 be?(1 point) Responses 75 amu 75 amu 107 amu 107 amu 219 amu 219 amu 73 amu 73 amu

Answer 1

To determine the atomic mass of Fe(OH)3, we need to add up the atomic masses of each individual atom in the formula.

Fe has an atomic mass of 56 amu,
O has an atomic mass of 16 amu,
and H has an atomic mass of 1 amu.

In Fe(OH)3, there is 1 Fe atom, 1 O atom, and 3 H atoms.

Atomic mass of Fe(OH)3 = (56 amu) + (16 amu) + (3 * 1 amu)
= 56 amu + 16 amu + 3 amu
= 75 amu

So, the atomic mass of Fe(OH)3 is 75 amu.
