how many grams of sulfur are needed to react w/ 246 grams of mercury to form HgS?

Hg + S ==> HgS unless your instructor insists on writing S as S8, in which case it will be
8Hg + S8 ==> 8HgS.

The answer will be the same no matter which way the equation is written. I shall be happy to check your work. This is freshman chemistry stoichiometry.
