Ksp for Ag2CO3 (molar mass = 276 g/mol) is 3.50x10-6. Into a 100.00 mL saturated Ag2CO3 solution, 0.0200 mol of Na2CO3 solid is added. How many grams (3 sig fig) of solid will precipitate? (hint: find how many moles of Ag2CO3 is dissolved in pure water, and how many moles is dissolved in Na2CO3 solution. The difference is how many moles will precipitate out from solution.)
