✔ 最佳答案
假設 H2SO4 完全電離。H2SO4(aq) → 2H+(aq) + SO42-(aq)
摩爾比 H2SO4 : H+ = 1 : 2
H2SO4(aq) 的摩爾數 = 0.2 x (50/1000) = 0.01 mol
溶液中 H+ 的摩爾數 = 0.01 x 2 = 0.02 mol

Number of mole of H2SO4=50/1000 x 0.2
=0.01mol
Number of mole of hydrogen ion=0.01x2
=0.02mol
=0.01mol
Number of mole of hydrogen ion=0.01x2
=0.02mol
