Hi Sace:

Have you looked at a source, like Wikipedia:

https://en.wikipedia.org/wiki/Mole_(unit) ?​

If not, I think the WIkipedia article is likely to be helpful.

Regards,

I don't think there's any point in a Socratic dialogue to squeeze the answer out of you. You can write the formula AlO₃H₃, the Al , the O₃ and the H₃ can in principle be in any order you like; however it's more conventional to write it Al(OH)₃ which is more indicative of structure, the way the atoms hang together. If you're somewhat prepared that should illuminate you immediately, if it doesn't there is nothing for it but to read yr textbook.

I thought that much more effort needed to go into that and I over complicated it for sure.
