One gram of the silver salt of an organic dibasic acid yields, on strong heating, 0.5934 g of silver. If the weight percentage of carbon in it is 8 times the weight percentage of hydrogen and one-half the weight percentage of oxygen, determine the molecular formula of the acid. [Atomic weight of Ag = 108]
(1) C4H6O4
(2) C4H6O6
(3) C2H6O2
(4) C5H10O5

(2) is correct answer because h and o will have same mole from  given composition in emperical formula.
  • -63
(B) is the correct answer
  • -16
And is B

As weight of silver is given after heating is 0.6g so weight of acidic part is 0.4g by the given weight of Ag we can find moles of Ag by this we can find moles of compound.moles of compound = moles of Ag / 2 this 2 is due to dibasic acid
