2 Ag + S Ag2S -----------> [balanced equation] AG = 2 x 107.87 = 215.74 S = 1 x 32.06 = 32.06 So ... Ag2S molar mass = 247.8 g / mol Number of moles in 25 grams = 25 g / 247.8 g / mol = 0.1 moles of Ag2S in 25 g of the balanced equation ... 2 mol Ag needed to produce 1 mol Ag2S therefore 0.2 mole of Ag is required to produce 0.1 mol Ag2S ... calculate weight in grams, present in 0.2 mol Ag Ag Ag = 0.2 mol x 107.87 g / g = 21.574 moles of money Answer: 21.574 grams
