Answer:
Step-by-step explanation:
Baking soda decomposes to produce sodium carbonate .
2NaHCO₃ = Na₂CO₃ + CO₂ + H₂O.
2 x 84 g 106 + 10 x 18 g
Molecular mass of Na₂CO₃ .10H₂O = 286
168 g baking soda produces 286 g sodium carbonate
1.555g baking soda will produce 286 x 1.555 / 168
= 2.647 g
Percentage yield = actual yield / theoretical yield x 100
= ( .991 /2.647 ) x 100
= 37.43 %.
