Question
How many liters of hydrogen will be produced when 3766 g of aluminum are combined with hydrobromic acid to make aluminum bromide?
Answers

2Al + 6HBr ==> 3H2 + 2AlBr3
mols Al = grams/atomic mass = ?
Using the coefficients in the balanced equation, convert mols Al to mols H2 gas.
Now convert mols H2 gas to liters knowing that 1 mol occupies 22.4 L at STP.
