JEE Main 2022 (25 Jun Shift 1)

Question

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____×10-3 m moles.

Correct answer
20

Step-by-step explanation

Initial moles of H2SO4 (in/Lit.) =0.02

In 50% solution moles of H2SO4=0.01 m moles

Added moles of H2SO4=0.01 m moles

Total moles of H2SO4 in resulting solution =0.02 m moles

=20×10-3 m moles

=20×10-3 milimoles
