    both shouldn't be h2so4

    there's even a equation for same solute...called Dilutional equation...

    does it give molarities for the two initial solutions? if not I haven't studied this.

    i got molarities of both separate..i dont know how to find volume..cuz for the equation i need separate volumes and total volume..

    @shubhamsrg @Peter14 Crap! sry i frgt to give u densities... the 30% one d=1.218 70% one d=1.61..both are g/ml

    the language of the question confuses me molarity = total moles/toatl volume. @Peter14 please continue! :| I am confused here.

    i'm confused here too. If I were you I would try to find a table or graph somewhere on how the concentration of h2so4 affects the density of a solution

    Also...molarity equals

    if you can't find that, I have no clue.

    (molarity of 1solute*its volume + m of 2nd solute*its volume)/total volume in litres

    @shubhamsrg does that formula help? @Peter14 goodnight...sry to have kept you awake...
