A mixture of and is heated until all the water is driven-off. If 5.0 gm of a mixture gives 3g of anhydrous salts, what is the percentage by mass of in the original mixture? **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

Official Solution

## ✅ Correct Answer: **C** ### 📖 Detailed Explanation: This question uses stoichiometry and limiting reagent. Write the balanced chemical equation, compute moles of each reactant, identify the limiting reagent, and use stoichiometric ratios (and % yield, if needed) to obtain the answer; this gives option C. --- *This is an official solution provided by Chem Mantra.
