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)\n75 amu\n73 amu\n219 amu\n107 amu

Answer

Explanation:

Step1: Calculate oxygen mass in Fe(OH)₃

There are 3 oxygen atoms. Each oxygen has atomic mass 16 amu. So mass of oxygen = 3×16 = 48 amu.

Step2: Calculate hydrogen mass in Fe(OH)₃

There are 3 hydrogen atoms. Each hydrogen has atomic mass 1 amu. So mass of hydrogen = 3×1 = 3 amu.

Step3: Add masses of iron, oxygen and hydrogen

Iron has atomic mass 56 amu. Total mass of Fe(OH)₃ = 56+48 + 3=107 amu.

Answer:

107 amu
