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
 
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 
 
 
The normality of the acid is 0.6659 N.
