Title: Reactions in aquous solutions
Post by: zezi1 on February 01, 2009, 11:18:59 PM

Hi guys.  I got the following problem:


"How many grams of H2 are produced by the reaction of 1.46g Al with 75 mL of 3.66 M HCl?"

I got the balanced equation as:
2Al + 6HCl -------) 2AlCl3 + 3H2

I am confused as to what to do next.  I can find the number of moles of each of the reactants, but i don't know where to go after that.  Thanks in advance.

Calculate moles of Al and HCl

Calculate moles of Al and HCl

Do i then determine a limiting reagent based on the mole ratio of the two reactants?
