The molecular weight and equivalent weight of which one of the following is the same ?

Answer»

`H_(2)SO_(4)`
`KMnO_(4)`
`H_(2)C_(2)O_(4)`
`NAOH`

SOLUTION :Both the molecular weight and equivalent weight for NaOH is 40.
Molecular weight of NaOH=23+16+1=40
Equivalent weight of NaOH
`=("Molecular weight of NaOH")/("ACIDITY of NaOH")=(40)/(1)=40`
