"12th grade" is not a subject, and you have not said what the chemical reaction is.
I assume it must be
2HCl + S2 ---> H2S + Cl2
First, balance the equation (I already did it here)
Then you convert the 20 grams of HCl into that amount in moles.
Then you find out how many moles of sulfuric acid will be produced according to stoichiometry.
Then convert the amount of sulfuric acid produced in moles into grams. That's how much will be produced
And that's the procedure on how to do it. I didn't do the math for you because you need to learn how to do it for yourself. :)
