A mixture consisting of 11.3 g of calcium fluoride, CaF2, and 13.0 g of sulfuric acid, H2SO4, is heated to drive off hydrogen fluoride, HF.
CaF2(s) + H2SO4(l) ==> 2HF(g) + CaSO4(s)
What is the maximum number of grams of hydrogen fluoride that can be obtained?

Classic stoichiometry problem! Here's a little outline that should help you:
Given: grams of reactants, to solve...
Find: moles of reactants
then moles of products (you have a balanced equation, right?)
Then grams of products
I hope this helps.
GEEKS RULE!

the procedure is the same as for your question of the decomposition of the sandstone.
you should do your homework by yourself
