Given:
Volume; V = 1 litre
Pressure; P = 1 atm
Temparature; T = 273 K
n = ?
We know,
![PV space equals nRT
straight n space equals space PV over RT
space space space equals fraction numerator 1 cross times 2 over denominator 0.0821 cross times 273 end fraction
space space straight n space equals space 0.0892 space mole](https://images.topperlearning.com/topper/tinymce/cache/7dc16e26356162c299460b711bbd6565.png)
Meq of NH3 = Meq of H2SO4
0.0821× 1000= 134×Normality of an acid
Normality of an acid =
![equals space fraction numerator 0.0892 cross times 1000 over denominator 134 end fraction
space equals space 0.6659 space straight N](https://images.topperlearning.com/topper/tinymce/cache/68bd21c73511b620ee37158a93f1c32d.png)
The normality of the acid is 0.6659 N.
