Easy INTEGER +4 / -1 PYQ · JEE Mains 2022

1 L aqueous solution of H2SO4 contains 0.02 m mol H2SO4. 50% of this solution is diluted with deionized water to give 1 L solution (A). In solution (A), 0.01 m mol of H2SO4 are added. Total m mols of H2SO4 in the final solution is ___________ $\times$ 103 m mols.

Answer (integer) 0

Solution

$\mathrm{n}_{\mathrm{H}_2 \mathrm{SO}_4}$ in $\mathrm{Sol}^{\mathrm{n}} \mathrm{A}=50 \%$ of original solution<br/><br/> $=0.01 \mathrm{~m} \mathrm{~mol}$.<br/><br/> $\mathrm{n}_{\mathrm{H}_2 \mathrm{SO}_4}$ in Final solution $=0.01+0.01$<br/><br/> $=0.02 \,\mathrm{m\,mol}$ <br/><br/>$=0.00002 \times 10^3 \mathrm{m\,mol}$<br/><br/> The answer 0
