A mixture of Xe and F₂ was heated. A sample of white solid thus formed reacted with hydrogen to give 56 ml of Xe at 0°C and 1 atm and HF formed required 60 ml of 0.25 M - NaOH for complete neutralization. If the molecular formula of the solid formed is XeFₓ, then the value of x is
Answer:
6.00
Solution:
Xe = 56/22400 = 0.0025 mol, so the XeFₓ sample = 0.0025 mol and HF = 0.0025x mol. NaOH = 0.060 × 0.25 = 0.015 mol = HF. So 0.0025x = 0.015 ⇒ x = 6 (XeF₆). Ans: 6.
