UPSC CDS Science Chemistry Questions Part 1

NaCl has the same equivalent weight and molecular weight.
The molecular weight of sodium chloride, NaCl, is [23 + 35 = 58].
Molecular weight divided by the valence of the compound gives equivalent weight.
Valence refers to how many hydrogen atoms would bond with the compound. For NaCl, thevalence is 1 because only one hydrogen atom could bond with NaCl.
Equivalent weight of NaCl is [5+8/1= 58].
Hence, for NaCl, molecular weight = 58 and equivalent weight = 58
