When is the molecular weight of an acid the same as its equivalent weight?
The molecular weight of an acid is equal to its equivalent weight if the acid donates only one proton (H+ ion) per molecule. This is because the equivalent weight of an acid is the molecular weight divided by the number of protons it donates.
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)
What is the equivalent weight of Ag?
equivalent weight of silver nitrate = 169.87 so 0.1 N Ag NO3 = 16.987 gm /litre of AgNO3 now equivalent weight of KCl = 74.55 so 0.1 N KCl = 7.455 gm/litre so 0.1 N AgNO3 = 0.1N KCl = 7.456 gm of KCl [ not mg ]
What is the equivalent weight of potassium bromate?
The equivalent weight of potassium bromate (KBrO3) is its molar mass divided by the change in oxidation number per mole of substance in a given reaction. The molar mass of KBrO3 is 167 g/mol, and since it undergoes a congruent reduction to KBr, the change in oxidation number is 1 per mole. Therefore, the equivalent weight of KBrO3 is 167 g/mol.
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.
What is KOH equivalent weight?
The equivalent weight of KOH (potassium hydroxide) is the molecular weight divided by the number of equivalents of the species. For KOH, since it donates one hydroxide ion (OH-), its equivalent weight is equal to its molecular weight (39.10 g/mol for K + 16.00 g/mol for O + 1.01 g/mol for H) divided by 1, giving an equivalent weight of 56.11 g/mol.
When is the molecular weight of an acid the same as its equivalent weight?
The molecular weight of an acid is equal to its equivalent weight if the acid donates only one proton (H+ ion) per molecule. This is because the equivalent weight of an acid is the molecular weight divided by the number of protons it donates.
Equivalent weight of sodium thiosulphate is equal to its molecular weight why?
The equivalent weight is the gram molecular weight divided by the number of electrons lost or gained by each molecule; e.g., potassium permanganate (KMnO4) in acid solution, 158.038/5 g; potassium dichromate (K2Cr2O7), 294.192/6 g; and sodium thiosulfate (Na2S2O3·5H2O), 248.1828/1 g. In case of Sodium Thiosulfate the reation proceeds as under: I2 + 2 Na2S2O3 → Na2S4O6 + 2 NaI 2 Na2S2O3 ≡ I2 ≡ Cl2 ≡ 2 e Hence Na2S2O3 ≡ 1 e Thus Molecular weight devded by 1 is the equivalent weight & hence both have same value

Do you divide equivalent fractions?
Any fraction divided by an equivalent fraction will always equal one.Any fraction divided by an equivalent fraction will always equal one.Any fraction divided by an equivalent fraction will always equal one.Any fraction divided by an equivalent fraction will always equal one.
How many mmol equal 52 meq of potassium?
Since potassium has a valence of one, its equivalent weight is the same as its molecular weight; therefore, 2.9.

Is weight and equivalent weight equal?
Yes, it is
What does normality mean in chemistry?
Normality is a way of expressing concentration, and is not used widely any more. It is the equivalent wt of a substance per liter of solution. The equivalent weight will depend on the reaction that take place, and can be the same as the molecular weight. Example: HCl has same equiv. wt. as mol. wt. because it has only 1 equivalent, i.e. one H. H2SO4 has TWO equivalents (2 H+) so, 1 molecular wt will be equal to 2 equivalent wts, and normality will be 2x the molarity.
What is the equivalent weight of potassium bromate?

What is Equivalent weight of boric acid?
The equivalent weight of boric acid (H3BO3) is equal to its molar mass divided by the number of protons that it can donate or accept in a reaction. Since boric acid can donate three protons in acid-base reactions, its equivalent weight is approximately 33 g/mol.
