No use of H2O because molarity not given so assuming its molarity to be 0 right????????????????????????

No! the molarity of water is always fixed at room temperature. It is 55.55M . Here , H+ions coming from water are way less than the ones coming from acid. Therefore, we ignore its H+and only consider its volume.

Ok so H+ ions are way less from H2O since it's a weak electrolyte right??????????????????????????????
