We can calculate the grams of chlorine reacted by using the product 11.7 g of sodium chloride.
NaBr + Cl- → Br- + NaCl
Mass of NaCl (molar mass of NaCl) → Moles of NaCl (mole-to-mole comparison) → Moles of Cl- (molar mass of Cl) → grams Cl-
When chlorine gas is bubbled into a solution of a sodium bromide, the sodium bromide reacts to give bromine, a red- brown liquid, and sodium chloride (table salt). A solution was made by dissolving 20.6g of sodium bromide in 100.0g water. After passing chlorine through the solution, investigators analyzed the mixture. It contained 16.0 g of bromine and 11.7 g of sodium chloride. How many grams of chlorine reacted?
