Elemental Sulfur can be formed through the combustion of Hydrogen Sulfide (found in Methane gas) give in equation H2S+O--->S + H2 4

Question

tell how much sulfur is made from 250 grams of methane
2 H2S + O2---->2S +2 H2O
s=32

Answer 1

The equation helps a LITTLE. In response to what I presume is your clarification to the earlier post, I quote from the above question, "tell how much sulfur is made from 250 grams of METHANE" and we can't answer that without some indication of how much S is in CH4.

Answer 2

There isn't enough information to answer the question. The equations you have listed have no CH4 in them so without knowing percent S in CH4 (or some way to calculate it) the 250 g CH4 means nothing because we can't convert that into grams S.
