Sulphuric acid reacts with sodium hydroxide as follows:

$$ \mathrm{H}_2 \mathrm{SO}_4+2 \mathrm{NaOH} \longrightarrow \mathrm{Na}_2 \mathrm{SO}_4+2 \mathrm{H}_2 \mathrm{O} $$

What will be the amount of sodium sulphate formed, when l L of 0.2 M sulphuric acid is allowed to react with l L of 0.2 M sodium hydroxide solution?

The molecular mass of sucrose $\left(\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}\right)$ is

How much volume of 1 N aqueous solution of $\mathrm{H}_2 \mathrm{SO}_4$ should be taken, which will contain 0.2 moles of $\mathrm{H}_2 \mathrm{SO}_4$ ?

For a given unbalanced reaction, $\mathrm{MnO}_2+\mathrm{HCl} \longrightarrow \mathrm{MnCl}_2+\mathrm{H}_2 \mathrm{O}$, which is the limiting reagent, if the initial amount for each of the reactant is 100 grams?

[Molar masses : $\mathrm{MnO}_2=86.9 ; \mathrm{HCl}=36.5 ; \mathrm{MnCl}_2 \left.=125.8 ; \mathrm{Cl}_2=70.9 ; \mathrm{H}_2 \mathrm{O}=18\right]$
