Normal Normality

Chemistry Level 2

When 100 ml of decimolar $$\ce{H2SO4}$$ is mixed with 500 ml of $$\ce{NaOH}$$ present in the same concentration, an acid-base solution is formed. Calculate the normality of that solution. If the normality can be expressed as $$N$$, express your answer as $$400N +3$$.
