What is the equivalent weight of Na2S2O3?

36
The equivalent weight is the gram molecularweight divided by the number of electrons lost or gained byeach molecule; e.g., potassium permanganate (KMnO4) in acidsolution, 158.038/5 g; potassium dichromate (K2Cr2O7), 294.192/6 g;and sodium thiosulfate (Na2S2O3·5H2O), 248.1828/1g.


Likewise, people ask, what is the equivalent weight of Na2CO3?

Equivalent Weight = Molar weight of theCompound ÷ Charge on the Compound. So, Gram EquivalentWeight of CaCO3 = 100 ÷ 2 = 50. The numbers ofelectronic charge on cation of Na2CO3 is 2.

Also, what is the relative formula mass of Na2S2O3 5h2o? ENDMEMO
Name: Sodium Thiosulfate Pentahydrate
Formula: Na2S2O3.5H2O
Molar Mass: 248.1841

Likewise, what is the molecular weight of Na2S2O3?

158.11 g/mol
