If a typical antacid tablet contains 2.0 g of sodium hydrogen carbonate, how many moles of carbon dioxide should one tablet yield? compare this theoretical value with your results. (hint: you will first need to convert your mass into moles by dividing by the molar mass of nahco3 or sodium hydrogen carbonate a/k/a baking soda). , show all work and think about mole ratios relating co2 to nahco3.

Given mass of sodium hydrogen carbonate = 2.0 g

First, calculate the number of moles of sodium hydrogen carbonate.

Number of moles =       (1)

Molar mass of sodium hydrogen carbonate = 84 g/mol

Put the values in formula (1)

Number of moles =

= 0.023 mol

Sodium hydrogen carbonate is used to neutralise hydrogen chloride present in the stomach.

The reaction is as follows:

Here, 1 mole of sodium hydrogen carbonate gives 1 mole of carbon dioxide.

Thus, number of moles of sodium hydrogen carbonate is equal to number of moles of carbon dioxide.

0.023 mol of sodium hydrogen carbonate gives 0.023 mol of carbon dioxide for one tablet.
