Answer
6.116 grams of sulfur
Work Step by Step
You start with 6.500 g of hydrogen sulfide (chemical formula: H$_{2}$S) and if since it decomposes into only 2 elements, the amount of one element can be determined by subtracting the amount of the other element from the total mass. If 0.384 g of hydrogen is produced, 6.500 g - 0.384 g = 6.116 g of sulfur produced.
