The compound Fe(NO3)3 is known as Iron(III) Nitrate.
To break it down, we start with the iron (Fe) which has a charge of +3 in this compound. The presence of the nitrate ion (NO3–) signifies that we have three of these nitrate ions paired with one iron ion to balance the charge. Since iron can have multiple oxidation states, the (III) specifies that iron is in the +3 oxidation state in this particular compound. Therefore, the full name reflects both the metal and its oxidation state, resulting in Iron(III) Nitrate.
