The amount of sodium bromide that would be formed from the reaction will be 7.5524 grams
Stoichiometric calculation
Looking at the equation of the reaction:
[tex]CuBr_2 + 2NaCl --- > CuCl_2 + 2NaBr[/tex]
The mole ratio of CuBr2 and NaCl is 1:2.
Mole of 16.4 grams of CuBr2 = 16.4/223.37
= 0.0734 moles
Mole of 22.7 grams of NaCl = 22.7/58.44
= 0.3884 moles
Equivalent mole of NaCl = 0.1468 moles
Thus, NaCl is in excess while CuBr2 is limiting.
Mole ratio of CuBr2 and NaBr = 1:1
Mass of 0.0734 mole NaBr = 0.0734 x 102.894
= 7.5524 grams
