1) An aqueous solution was prepared by dissolving 87.750 g of K2CO3 (potassium carbonate) in 225.00 g of water. It was found that a 10.00-ml sample of this solution had a mass of 12.755 g. (FW of K CO. = 138.204) NOTE: You may often see your instructor use the abbreviation FW, which means Formula Weight. Technically, FW...
