Tīmeklis2024. gada 30. aug. · By dividing by 3.4 mol HI / L on both sides, we get: We are left with X = 1.2 L. The answer is 1.2 L of 3.4 M HI required to reach the equivalence point with 2.1 L of 2.0 M KOH. Alternatively, as the required mole ratio of HI to KOH is 1:1, we can use the equation M1V1 = M2V2 to solve the problem: (3.4 M) (V 1) = (2.1 L) (2.0 M)

Therefore, the molar concentration of water is c (H 2 O) = 1000 g/L 18.02 g/mol ≈ 55.5 mol/L. Likewise, the concentration of solid hydrogen (molar mass = 2.02 g/mol) is c (H 2) = 88 g/L 2.02 g/mol = 43.7 mol/L. room assignment chem tech 2021
