    Chem P3 error %?

    what is the % range for which the titre value obtained by us to the one obtained by the supervisor considered to be accurate one? if the titre is lets say approx 30 cm^3 then to which range do we get the full and the least mark?

    the perfect titre......!!!!!

    hey! i got messed up with the given mass of chemical to conduct the titration. so measured mass was a bit low. thus this soln with low conc. changed the titre value to 24. But the % which was to be calculated at last is the same one. Does this affect much with the marking?

    physics A2 help

    think this way! FLR is for the interaction of two fields. It gives the dirn of force experienced. FRR if the question is dealing with the electromagnetic induction then it is this rule which works. Here 1 field is present which gives rise to the next field due to the induction. Did this...
