55.847 (mass of Fe) + 3(15.999) (mass of 3 oxygen's) = 103.844 g

there is one Iron, Fe, and 3 Oxygen, O. So you add the Fe, 55.847 + 3*15.999, which is the mass of oxygen. the mass of oxygen is 15.999 but since there are 3 of them you have to multiply 3 and 15.999 and add that to 55.847 to get the total mass which is 103.844 g.

To find the mass of the formula, you look at the periodic table Fe = ______ g O = 3( ______)g you mutiply by three b/ there are 3 oxygens. You then proceed to add evrything to get the mass.

Since there is one Iron, Fe. the mass is 55.487. The mass of 3 oxygen's is 47.997. Add 55.487 and 47.997 and you get 103.844
