1 L aqueous solution of H 2 SO 4 contains 0 . 02 m mol H 2 SO 4 . 50 % of this solution is diluted with deionized water to give 1 L solution A . In solution A , 0 . 01 m mol of H 2 SO 4 are added. Total m mols of H 2 SO 4 in the final solution is____ × 10 - 3 m moles .,

MARKS App · Accepted Answer

Initial moles of H 2 SO 4 (in/Lit.) = 0 . 02 In 50 % solution moles of H 2 SO 4 = 0 . 01 m moles Added moles of H 2 SO 4 = 0 . 01 m moles Total moles of H 2 SO 4 in resulting solution = 0 . 02 m moles = 20 × 10 - 3 m moles = 20 × 10 - 3 milimoles
