    It contains 3 molecules wouldn't be quite accurate. A molecule is something like H2O. And what is given in the question is itself a molecule. If there were 3 of them it would be: \[3Al(OH)_3\]

    Yep. |dw:1364524588055:dw| The reason why it is 3 OH groups and not just 3 H is because of the parentheses around the (OH)

    haha. It's okay, they can be tricky to understand at first. (though, it may be better to ask the chemical ones under the chemistry section in the future, they'll be more likely to explain things)
