Question

What volume of O2 gas (in L), measured at 770mmHg and 33∘C, is required to completely react with 52.6g of Al?

Answer 1

I have two comments for this problem that might help you.

I think it is clear from the information given that we are going to need the Ideal Gas Law. We have a pressure, temperature, and at least some indication of a quantity in moles. That's where my second comment will lead to.

The key word here is "reacts." We have a chemical reaction going on. So we might want to create a (balanced) chemical equation! That way, we can use stoichiometry to convert 52.6 g of Al into moles of O2, and thus apply this in the Ideal Gas Law equation.

Good luck with the problem! If you still need help, feel free to bump the question or tag someone / ask for clarification!
