5 moles of sodium bromide molecules are produced in the given chemical reaction.
Explanation: For the reaction of bromine and sodium carbonate, the balanced chemical reaction will be:
3Br2 + 3Na2CO3 → 5NaBr + NaBrO3 + 3CO2
By Stoichiometry,
3 moles of bromine reacts with 3 moles of sodium carbonate to produce 5 moles of sodium bromide, 1 mole of sodium bromate and 3 moles of carbon dioxide gas.
From the above stoichiometry, it is visible that 5 moles of NaBr are produced in the given chemical reaction.
