One Way of Obtaining Pure Sodium Carbonate Is Through the Decomposition

Multiple Choice

One way of obtaining pure sodium carbonate is through the decomposition of the mineral trona, Na₃(CO₃) (HCO₃) ·2H₂O. 2Na₃(CO₃) (HCO₃) ·2H₂O(s) → 3Na₂CO₃(s) + CO₂(g) + 5H₂O(g)
When 1.00 metric ton (1.00 × 10³ kg) of trona is decomposed, 0.650 metric ton of Na₂CO₃ is recovered. What is the percent yield of this reaction?

A) 92.4%
B) 72.1%
C) 65.0%
D) 48.1%
E) 35.0%
