Question

2. Assume the reaction is: 2 NaHCO3 (s) ? Na2CO3 (s) + CO2 (g) + H2O (g) What mass of NaHCO3 (s) must have been present at the beginning of the reaction? Hint: Your goal is to do the steps you did in the previous section, but in reverse. You know the mass of the Na2CO3 product: 5.09g The molar mass of Na2CO3 is 105.99 g/mol The molar mass of NaHCO3 is 84.01 g/mol How can you use this information to find the mass of the initial amount of NaHCO3?

Step 1

First, we need to find the number of moles of NaCO3 produced in the reaction. We can do this by dividing the mass of NaCO3 produced (5.09g) by its molar mass (105.99g/mol): Number of moles of NaCO3 = 5.09g / 105.99g/mol = 0.048 moles Show more…
