1L aqueous solution of H _ 2 SO _ 4 contains 0 . 02mmol H _ 2 SO _...

1L1L aqueous solution of H2SO4{H}_{2}{SO}_{4} contains 0.02mmolH2SO4.500 . 02mmol{H}_{2}{SO}_{4} . 50 % of this solution is diluted with deionized water to give 1L1L solution \left(A\right).Insolution(A). In solution \left(A\right), 0.01mmolofH2SO40 . 01mmol of {H}_{2}{SO}_{4} are added. Total mm mols of H2SO4{H}_{2}{SO}_{4} in the final solution is____×10−3mmoles\times {10}^{- 3}mmoles.

Correct answer

0

Step-by-step solution

Initial moles of H2SO4{H}_{2}{SO}_{4} (in/Lit.) =0.02= 0 . 02

In 5050 % solution moles of H2SO4=0.01mmoles{H}_{2}{SO}_{4} = 0 . 01mmoles

Added moles of H2SO4=0.01mmoles{H}_{2}{SO}_{4} = 0 . 01mmoles

Total moles of H2SO4{H}_{2}{SO}_{4} in resulting solution =0.02mmoles= 0 . 02mmoles

=20×10−3= 20 \times {10}^{- 3} m moles

=20×10−3= 20 \times {10}^{- 3} milimoles
