I don't really understand this. Will someone please help me to solve this problem?

Iron III nitrate solution reacts with lithium hydroxide solution to produce solid iron III hydroxide and lithium nitrate solution. Write a balanced equation. How many moles of lithium nitrate are produced when 3 moles of iron III nitrate eact? How many moles of lithium hydroxide are needed to produce 6.3 moles of iron III hydroxide?

With the "iron III" is that like 3FE or something?

I'm lost.  ???  Please help me out! Thanks a bunch!!

Iron III = Fe3+

First write a balanced reaction equation

The roman numerals that come after a metal denote the oxidation state of the metal in the compound.

In this case, as devadevil already said, it's Fe+3 because you have iron (III) nitrate.
