What is the equivalent weight of feso4?
151.8
-Equivalent weight of ferrous sulphate = molecular weight of ferrous sulphate/ involved electron. So, equivalent weight of ferrous sulphate which is present as reductant is 151.8 which is equal to the molecular weight of ferrous sulphate.
How do you calculate equivalent weight of iron?
Iron (atomic weight 55.845) has an equivalent weight of 27.9225 in ferrous compounds (valence 2) and 18.615 in ferric compounds (valence 3). The weight proportion in which elements or radicals combine to form compounds can be determined from their equivalent weights.
What is the correct name of Fe2O3?
Ferric Oxide (fe2o3)
What is the equivalent weight of K2Cr2O7?
Equivalent weight of K2Cr2O7 is 49 g/mol.
What is N factor in equivalent weight?
n factor is atomic weight or molecular weight by equivalent weight. n factor for acids is its basicity, ie, number of replaceable hydrogen ion per molecule. For exampleg HCl has n factor 1 n H2SO4 has 2 H3PO3 has n factor 2 because when H3PO3 dissociates to form H+ and HPO3^-2.
What is the weight of Fe?

The equivalent mass of Fe in FeO is (Fe = 56).
What is the mass of 5 moles of Fe2O3?
mol Fe 2 O 3 = 5 mol molar mass Fe 2 O 3 = 159.69 g/mol 85\% (210 ratings)
What is the correct chemical name for Fe2O3?
The chemical name for Fe2O3 is iron (III) oxide, which is also called ferric oxide . This compound is inorganic, red-brown in color and odorless.
How do you calculate molecular mass?
Molecular mass may be calculated by taking the atomic mass of each element present and multiplying it by the number of atoms of that element in the molecular formula. Then, the number of atoms of each element is added together.
What is the standard enthalpy of Fe2O3?
Elements in their standard state have an enthalpy of formation value of zero. The standard enthalpies of formation of Fe2O3 and Al2O3 are: H of Fe2O3(s) = -825.5 kJ/mol. H of Al2O3(s) = -1675 kJ/mol. Express your answer to three significant figures and include appropriate units.
