Question

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

Answer 1

@Peter14

Answer 2

re-check the question -_-

Answer 3

why?

Answer 4

both shouldn't be h2so4

Answer 5

that's what I was thinking too

Answer 6

why not?

Answer 7

oh,,well, it can be, okay, let it be..

Answer 8

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

Answer 9

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

Answer 10

no...i gave u the whole question..

Answer 11

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

Answer 12

@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

Answer 13

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

Answer 14

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

Answer 15

Also...molarity equals

Answer 16

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

Answer 17

and I have to go now, it's 22:37 which is past my bedtime

Answer 18

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

Answer 19

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

Answer 20

thats just the formula I wrote -_-

Answer 21

so? what to do?

Answer 22

not too sure, I wouldn't direct you wrong. Not too sure on this one.

Answer 23

hmm..ok..one sec there's one more..
