4) Hypothetical Data for Analysis An oxide of iron is 69.94% iron by mass. Calculate its empirical formula and determine the name of the ionic compound. (Hint: assume you have a 100 g sample of the oxide of iron. How many grams would be iron? Then how many grams would be oxygen? Convert those to moles. Find the ratio. Find the nearest whole number ratio). Then determine its name.
