Cоnsider the fоllоwing reаction: Nа2S (аq) + 2 AgNO3 (aq) → 2 NaNO3 (aq) + Ag2S (s) A 20.00 mL (milliliters) sample of 0.260 M Na2S is reacted with 25.00 mL of 0.315 M AgNO3. Calculate the amount in grams of Ag2S produced in this reaction and provide the intermediate results as requested below. Use this molar mass for Ag2S: 247.8 g/mol Give the moles of Na2S Give the moles of AgNO3 Give the moles of Ag2S (consider the limiting reactant) Give the mass in grams of Ag2S Write all of these 4 numbers (results) in the answer box, but you also must send your work with units by email after you complete the entire exam.
