Question

Gram equivalent weight of FeSO4

Answer 1

Gram equilant weight is defined as: “The mass of a substance especially in grams that combines with or is chemically equivalentto eight grams of oxygen or one gram of hydrogen :the atomic or molecular weight divided by the valence”.

Ferrous sulphate is found in three forms in nature and there respective weight are as follows:

 

Ferrous sulphate (hydrated) {Green vitriol}......FeSO 4. 7H 2O......M.W./1 = 278.00 Ferrous sulphate (anhydrous)..........FeSO 4......M.W./1 = 152.00 Ferrous ammonium sulphate (Mohr's salt).....FeSO 4. (NH 4) 2SO 4.....M.W./1 = 392.14

Answer 2

the gram Equivalent weight of feso4 is 152 as the atomic weight of elements 56 sulphur is 32 and oxygen 16 when multiply 2 4 64 bit is equal to 1 52
