try to do an experiment about hydrogen embrittlement, but I don't know how to prepare the solution. The equation is FeS+HCl-->H2S+FeCl. how to prepare it? and how to find out the exact volume of the chemical thing to be use and the rate of H2s to be produce?

Hydrogen sulphide is exceedingly toxic. You should NOT be trying to generate it under any circumstances unless you know exactly what you're doing.
And you don't.

Preparation Of H2s Gas

Heat 3.2g of S and 5.6g of Fe together.
Let the product cool, and then add dilute hydrochloric acid!
The rate at which the gas is given off will depend on how finely you grind up the FeS (iron(II) sulphide).
The equations are Fe + S ---> FeS
and
FeS + 2HCl ----> FeCl2 + H2S

If all you want is to produce H2S gas in the lab, I would take the easy way out and eat some beans for dinner. I'm not sure on how you would grade it, though. Would you go for distance? Loudness? Whether paint peels off the walls?
