The 36th one

The 36th one 3 35. o, f 61 311,0 Equivalent weight OCO, (With tnolecular weight M) is : (3) M/24 What weight of IINO is needed to convert 5 gm of iodine into iodic acid according to the reacti 1: + HNO, HID + NO: + (l) 12.4 gm (2) 24.8 gm (3) 0.248 gm (4) 49.6 gm The number of mole of potassium salt i.e. oxidised by one mole of perman ion is :- (1)2/5 36. In the reaction V'O + Fe:O: FeO+ V20, the equivalent weight of V:O, is equal to its mol. wt. (I) mol. (2) 8 37. In the following change, 3Fe+4H20 Feo +414. mol.wt. (3) 6 (4) None of these Ifthe atomic weight ofiron is 56, then its equivalent be (2) 21 (3) 63 In the reaction :-

Dear Student,

Please find below the solution to your asked query:

State of V in VO is +2 But in V₂O₅ is +5

therefore change in O.S. is +3

Let's consider M as a molecular weight of V₂O₅

T h u s, e q u i v a l e n t w t = \frac{M}{(n \times n o . o f V a t o m s)} e q u i v a l e n t w t = \frac{M}{3 \times 2} = \frac{M}{6}

Hope it Helps!!
