Question

When 262 g of xenon (atomic mass = 131) reacted completely with 152 g of fluoride (atomic mass = 19), a mixture of XeF₂ and XeF₆ was produced. The molar ration XeF₂ : XeF₆ is

(A)  1 : 2

(B)  1 : 4

(C)  1 : 1

(D)  1 : 3  

Answer 1

Correct option  (C) 1 : 1

Explanation:

∴  moles of Xe F₂ formed = 0.5

moles of XeF₆ formed = 0.5 

∴  moles ratio = 1 : 1
