Question

The molecular mass of an organic acid was determined by the study of its barium salt. 4.290 g of salt was quantitatively converted to free acid by the reaction with 21.64 mL of . The barium salt was found to have two mole of water of hydration per ion and acid is mono basic. What is molecular weight of anhydrous acid?

**Options:**
- **A.** [object Object]
- **B.** [object Object]
- **C.** [object Object]
- **D.** [object Object]

---
**Difficulty:** HARD | **Chapter:** Mole concept | **Topic:** Basic stoichiometry, POAC, percent yield & limiting reagent

Accepted Answer

## ✅ Correct Answer: **A**

### 📖 Detailed Explanation:
This question uses empirical and molecular formula, volumetric analysis & stoichiometry. Relate mass, moles and number of particles using the mole concept and basic stoichiometry; doing the algebra gives the value listed in option A.
