Calculate the theoretical yield of CO2 based on the 3.5 g of NaHCO3 and record a grams to grams three step conversation

Answer 1

I assume the reaction is decomposition, NaHCO₃ --> NaOH + CO₂ (balanced as is).

Conversion step 1, grams to moles: (3.5g NaHCO₃) * (1 mol NaHCO₃ / 84.0g NaHCO₃) = 0.041₇ mole of NaHCO₃ (I carry one more digit than is significant for a more precise final answer).

Step 2, moles of NaHCO₃ to moles of CO₂ from balanced reaction: (0.041₇ mol NaHCO₃) * (1 mol CO₂ / 1 mol NaHCO₃) = 0.041₇ mole of CO₂.

Step 3, moles to grams of CO₂: (0.041₇ mol CO₂) * (44.0g CO₂ / 1 mol CO₂) = 1.8g theoretical yield of CO₂.
