Question

gram Equivalent mass of hno3

Answer 1

Answer:

63.0

Explanation:

The gram equivalent mass of HNO3 is 63.0.

=Mass of hydrogen +Mass of Nitrogen +(Mass of Oxygen)*3

=1+14+48

=63

Answer 2

Gram Equivalent mass of  $HNO_3$ is 63 g

Explanation:

Equivalent weight is calculated by dividing the molecular weight by n factor.  

${\text{Equivalent weight}}=\frac{\text{Molecular weight}}{n}$

n= basicity, for acids  , For $HNO_3$ , n = 1

$HNO_3\rightarrow H^++NO_3^-$

As $HNO_3$ dissociates to give 1 $H^+$ and thus it has basicity of 1.

Molecular mass of  $HNO_3$ = 1+14+3(16) = 63 g

${\text{Equivalent weight}}=\frac{63}{1}=63g$
