How many moles of CO2 are produced from 15.6 grams of NaHCO3?

Answer 1

Write equation: 2NaHCO₃ --> Na₂O + H₂O + 2CO₂ by decomposition

NaHCO₃ + HCl --> NaCl + H₂O + CO₂ rxn of sodium bicarbonate with acid

Either way, it's 1 mole CO₂/ 1 mole of NaHCO₃ or 2/2 = 1

Use Factor Labeling: Start with what you know

15.6 g SB (1 mole/84.01 g SB) (1 mole CO₂/mole of SB) = moles CO₂
