D)4.0 g

Question

Quizplus · Accepted Answer

The reaction between sodium hydroxide (NaOH) and carbon dioxide (CO2) to produce sodium hydrogen carbonate (NaHCO3) can be represented by the balanced chemical equation: NaOH + CO2 → NaHCO3. The molar mass of NaOH is approximately 40 g/mol, and the molar mass of NaHCO3 is approximately 84 g/mol. Given that 4.0 g of NaOH is used, this corresponds to 0.1 mol of NaOH. Since the reaction is a 1:1 mole ratio, 0.1 mol of CO2 is also required. The molar mass of CO2 is approximately 44 g/mol, so 0.1 mol of CO2 weighs about 4.4 g.
