Balanced Chemical Equation
The balanced chemical equation for the reaction of Br2 with Na2CO3 in aqueous solution is:
Br2 + Na2CO3 → NaBr + NaBrO3 + CO2
Number of Sodium Bromide Molecules Involved
From the balanced chemical equation, it is clear that one molecule of Br2 reacts with one molecule of Na2CO3 to give one molecule of NaBr and one molecule of NaBrO3. Therefore, the number of sodium bromide molecules involved in the reaction is:
2 NaBr
However, it is important to note that the question asks for the number of molecules of NaBr, not the number of moles or the mass. Therefore, we need to convert the number of moles of NaBr to the number of molecules of NaBr.
Molar Mass of NaBr
The molar mass of NaBr is:
NaBr = 1 Na + 1 Br = 22.99 g/mol + 79.90 g/mol = 102.89 g/mol
Number of Moles of NaBr
To find the number of moles of NaBr, we need to know the amount of Na2CO3 that reacts with Br2. Let's assume that we have 1 mole of Na2CO3. From the balanced chemical equation, we can see that 1 mole of Na2CO3 reacts with 1 mole of Br2 to give 2 moles of NaBr. Therefore, the number of moles of NaBr is:
1 mole of Na2CO3 × 2 moles of NaBr/1 mole of Br2 = 2 moles of NaBr
Number of Molecules of NaBr
To find the number of molecules of NaBr, we need to multiply the number of moles of NaBr by Avogadro's number. Avogadro's number is 6.022 × 1023 molecules/mol. Therefore, the number of molecules of NaBr is:
2 moles of NaBr × 6.022 × 1023 molecules/mol = 1.2044 × 1024 molecules of NaBr
Rounding off to the nearest whole number, the answer is:
5 molecules of NaBr
The balanced chemical equation for the reaction of Br2 with Na2CO3 in aqueous solution is:
Br2 + Na2CO3 → NaBr + NaBrO3 + CO2
Number of Sodium Bromide Molecules Involved
From the balanced chemical equation, it is clear that one molecule of Br2 reacts with one molecule of Na2CO3 to give one molecule of NaBr and one molecule of NaBrO3. Therefore, the number of sodium bromide molecules involved in the reaction is:
2 NaBr

2 moles of NaBr × 6.022 × 1023 molecules/mol = 1.2044 × 1024 molecules of NaBr
Rounding off to the nearest whole number, the answer is:
5 molecules of NaBr
