A)2.34 N
B)0.780 N
C)0.147 N
D)0.0865 N
E)0.288 N

Normality (N) is calculated using the formula: Normality = (grams of solute / (molar mass * volume of solution in liters)) * valence. For citric acid, a triprotic acid (valence = 3), dissolving 37.5 g in 0.250 L: Normality = (37.5 g / (192.14 g/mol * 0.250 L)) * 3 = 2.34 N.
