If 0.366 g of hydrogen is obtained in this experiment, how many grams of sulfur must be obtained

Missing  part  of  question if 6.200g H2S   decomposes ,  how  many  grams  of  sulfur  must be  obtained
2H2S--->2H2  +  S2
answer=  total  mass-  mass  of  the  H2  obtained
total  mass=6.200g
mass  of  hydrogen=0.366g
therefore  mass  of  sulfur  is  equal  to
  6.200g-0.366g5.834g

The empirical formula would be CH4.

“To get the empirical formula of the compound, we convert each mass percentage to mole percentage by dividing each to corresponding molar mass. 75% mass of carbon is 6.25 while 25% hydrogen is 25. We divide 25 by 6.25, we get 4. Hence, the empirical formula is CH4.”
