What would be the molarity of the solution obtained by mixing 30% by mass concentration of h2so4 and 70% by mass of h2so4. If the resultant solution has a density 1.425 g/ml.Calculate molarity

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
