Refer to the Periodic Table for Atomic Masses.
H2C3H2O4
2 x H = 2 x 1 = 2
3 x C = 3 x 12 = 36
2 x H = 2 x 1 = 2
4 x O = 4 x 16 = 64
2 + 36 + 2 + 64 = 104 is the Relative Molecyualr mass / Molar mass.
NB
I think this substance could be 'Propandioic Acid' ' HOOC- CH2 - COOH'.

What is the equivalent weight of boron?
Boron is a chemical with a symbol of B and an atomic number of 5. The equivalent weight of boron is dependent on the chemical that it is combining with.
What is the equivalent weight in grams of H2SO4?
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
In the reaction of sodium thiosulphate and iodine in aqueous medium the equivalent weight of sodium thiosulphate is equal to what?
The equivalent weight of sodium thiosulfate in the reaction with iodine is equal to its molar mass divided by the change in oxidation state of sulfur during the reaction. Since sulfur in thiosulfate changes from +6 to +2 during the reaction, the equivalent weight would be the molar mass of thiosulfate divided by 4.
How do you calculate equivalent weight of NH3?
The densities of NH3 at variable temperatures are - At boiling point - 0.86 kg/m3 At 15 oC - 0.73 kg/m3 At -33 oC - 681.9 kg/m3 (liquid) At -80 oC - 817 kg/m3 (transparent solid)
How do you calculate equivalent weight of lactic acid?
To calculate the equivalent weight of lactic acid, you need to consider the acid dissociation of lactic acid. Lactic acid has two acidic protons that can dissociate. The equivalent weight is calculated by dividing the molecular weight of lactic acid by the number of acidic protons it can donate in a reaction. For lactic acid, with a molecular weight of 90.08 g/mol and 2 acidic protons, the equivalent weight would be 45.04 g/eq.
What is the unit of equivalent mass?
The unit of equivalent mass is grams per equivalent (g/eq) or milligrams per equivalent (mg/eq). It represents the mass of a substance that can either donate or accept one mole of electrons in a redox reaction.
What is the equivalent weight of boron?
Boron is a chemical with a symbol of B and an atomic number of 5. The equivalent weight of boron is dependent on the chemical that it is combining with.
Whats the formula for mass?
1 Equivalent = 1 Mole / (number of moles per Eq.) Eq. mass = Molar mass / (number of moles per Eq.) N = Eq. concentration (eq/L) = Molar conc.(mol/L) / (number of moles per Eq.) = M / (mol/eq)
What is does eq stand for?

How to convert sulfuric acid formula weight to normality?
Sulfuric acid has a formula weight of 98 - but it has two protons and thus a functionality of two. Equivalent weight = molecualr weight/functionality so sulfuric acid is 98/2 = 49 eq wt
What is the equivalent weight of FeSO4.7H2O?
The equivalent weight of FeSO4.7H2O is the molar mass (278 g/mol) divided by the number of electrons transferred in the redox reaction. Since Fe in FeSO4 can undergo a maximum of 2 electron transfers, the equivalent weight is 278 g/mol / 2 = 139 g/eq.
