when chlorine gas is bubbled into a solution of sodium bromide, the sodium bromide reacts to give bromine a red brown liquid and sodium chlorine. A solution was made by dissolving 20.0g of sodium bromide in 100.0 g of water. After passing through the solution, it contained 16.0 g of bromine and 11.7 g of sodium chloride. How many grams of chlorine reacted?
