Assume that 29.7 g of Al react with HCl
according to the equation
Al(s) + HCl(aq) −→ AlCl3(aq) + H2(g)
at STP. How many moles of Al react? Remember to balance the equation first.
Answer in units of mol.
How many moles of H2 are produced?
Answer in units of mol.
How much H2 at STP is produced?
Answer in units of L.

After working those other problems, what about this do you not understand. Explain in detail. And while you're at it, balanced the equation.

My balanced eq is
2Al + 6HCl - 2AlCl3 +3H2
so moles of H2 at STP will be 3x22.4 right?

I don't think so. mols Al = grams/atomic mass = ?
