100 ml decinormal HCl is mixed to 100ml seminormal H2SO4 solution . calculate the normality of resulting mixture.

Explanation

In molality, the mass of the solvent is considered. In molarity, volume of the solution is considered. Mass does not change withy temperature while volume changes. Hence, molality does not change with temperature but molarity changes. So, molality is better unit for expressing concentration than molarity.
