100 ml decinormal `HCl` is mixed to 100 ml seminormal `H_(2)SO_(4)` solution.
Calculate normality of resulting mixture.

Explanation

To solve the problem of finding the normality of the resulting mixture when 100 ml of decinormal HCl is mixed with 100 ml of seminormal H2SO4, we can follow these steps:

### Step 1: Understand the given concentrations
- HCl is given as decinormal (0.1 N), which can be expressed as:
\[ N_1 = \frac{1}{10} \text{ N} = 0.1 \text{ N} \]
- H2SO4 is given as seminormal (0.5 N), which can be expressed as:
...
