Help with these questions I have no clue where to start???

1.What volume (mL) of hydrogen gas, saturated with water vapor, will be obtained from a 0.1138 gram sample of alloy which is 73.2% Al? (Pbar=754.3 torr, T=21.2 C)

2. What volume in mL will the dry hydrogen gas from problem 1 occupy at STP?

3. Which of the following alloys can be analyzed by the method of this experiment? Show the balanced chemical equations for the alloys that can be analyzed. Give the reasons why some alloys cannot be analyzed by this method.

You have to show your attempts at solving the problem, this is a forum policy.

If you're interested, you can look at this thread:  http://www.chemicalforums.com/index.php?topic=82790.0 Its a very similar question.  That poster is a little behind you, so be sure you can at least work through their problem, before you try to tackle this one.
