To determine the atomic mass of Fe(OH)3, we need to know the atomic mass of each element and the number of each element in the compound.
Fe (iron) has an atomic mass of 56 amu.
O (oxygen) has an atomic mass of 16 amu.
H (hydrogen) has a mass of 1 amu.
In Fe(OH)3, there is 1 iron atom, 3 oxygen atoms, and 3 hydrogen atoms.
Atomic mass of Fe = 1 * 56 amu = 56 amu.
Atomic mass of O = 3 * 16 amu = 48 amu.
Atomic mass of H = 3 * 1 amu = 3 amu.
Therefore, the atomic mass of Fe(OH)3 would be:
56 amu + 48 amu + 3 amu = 107 amu.
So the correct answer is 107 amu.
To find the atomic mass of Fe(OH)3, you need to multiply the atomic mass of each element by the number of atoms present and add them together.
Fe has an atomic mass of 56 amu, and there is only one Fe atom in Fe(OH)3.
O has an atomic mass of 16 amu, and there are 3 O atoms in Fe(OH)3.
H has a mass of 1 amu, and there are 3 H atoms in Fe(OH)3.
Calculating the atomic mass:
Atomic mass of Fe(OH)3 = (atomic mass of Fe) + (atomic mass of O x number of O atoms) + (atomic mass of H x number of H atoms)
= 56 + (16 x 3) + (1 x 3)
= 56 + 48 + 3
= 107 amu.
To determine the atomic mass of Fe(OH)3, you need to calculate the total atomic mass of each element in the compound.
First, let's determine the atomic mass of Fe(OH)3:
The atomic mass of iron (Fe) is 56 amu.
The atomic mass of oxygen (O) is 16 amu.
The atomic mass of hydrogen (H) is 1 amu.
In Fe(OH)3, there is one iron atom, three oxygen atoms, and three hydrogen atoms. To calculate the atomic mass, you need to multiply the atomic mass of each element by its respective number of atoms and then add them up.
Atomic mass of Fe(OH)3 = (Atomic mass of Fe) + (Atomic mass of O) * 3 + (Atomic mass of H) * 3
Calculating this:
Atomic mass of Fe(OH)3 = 56 + (16 * 3) + (1 * 3)
Atomic mass of Fe(OH)3 = 56 + 48 + 3
Atomic mass of Fe(OH)3 = 107 amu
Therefore, the correct answer is 107 amu.
