The equivalent weight or gram equivalent weight (GEW) for a strong mineral acid is the molecular weight (MW) divided by the number of replaceable hydrogen ions. For a strong base like sodium hydroxide (NaOH) it is the MW divided by the number of replaceable hydroxide ions. The GEW is applicable to other types of chemical reactions and it is necessary to know what the reaction is in order to determine the GEW. This is a common theme in chemistry, you must know what the chemical reaction is in order to determine concentrations. For H2SO4: H2SO4 = 98.08 g/mole (MW)
H2SO4 has two replaceable protons (H+) & therefore has 2 equivalents (eq)
GEW = g/equivalents (eq) = MW/eq = g/mole X moles/eq H2SO4 GEW = 98.08/2 = 49.04 g/eq For HCl: HCl = 36.46 g/mole HCl has 1 replaceable proton & therefore has 1 equivalent HCl GEW= 36.46/1 = 36.46 g/eq You should be able to calculate this for NaOH, KOH and HNO3

How many grams of sulfuric acid are needed to react with 8 mol of ammonium hydroxide?
2NH4OH + H2SO4 >> (NH4)2SO4 + 2H2O 8 moles NH4OH (1mol H2SO4/2mol NH4OH)(98.086g H2SO4/1mol H2SO4) = 392.34 grams H2SO4 needed
What is the equivalent weight of 55 grams to ounces?
1.94oz
How many grams are there in 456 liters of H2SO4?
100% pure H2SO4 doesn't exist
What is the equilvalent weight?
Equivalent means finding something the same, so the equivalent weight of 1 kilogram in grams is 1000 grams, or the equivalent in pounds would be 2.2 pounds. These weights are all the same, so they are equivalent.
