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 are there in 456 liters of H2SO4?
To convert liters to grams, you need to know the density of the substance. The density of sulfuric acid (H2SO4) is approximately 1.84 g/mL. Since 1 liter is equal to 1000 mL, you would first convert 456 liters to mL (456,000 mL) and then multiply by the density to find the weight in grams (approximately 839,040 grams).
5 N H2SO4 What is percent?
To calculate the percent of a 5 N H2SO4 solution, you need to know the molarity (moles of solute per liter of solution) and the molecular weight of the solute. Once you have that information, you can use the formula: % = (molarity x equivalent weight) / 10. If you provide the molecular weight of H2SO4, I can help you calculate the percent.
