To find the normality of the resulting solution after mixing 20 ml of 0.2 N HCl and 40 ml of 0.4 N HNO3, and then diluting the mixture to a total volume of 100 ml, we can follow these steps: ### Step 1: Calculate the equivalent of HCl and HNO3 Normality (N) is defined as the number of equivalents of solute per liter of solution. For strong acids like HCl and HNO3, the normality is equal to the molarity because they completely dissociate in solution. 1. **Calculate the equivalents of HCl:** \[ \text{Equivalents of HCl} = \text{Normality} \times \text{Volume (L)} ...
