## Nikhil619 2 years ago 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

@Peter14

2. shubhamsrg

re-check the question -_-

3. Nikhil619

why?

4. shubhamsrg

both shouldn't be h2so4

5. Peter14

that's what I was thinking too

6. Nikhil619

why not?

7. shubhamsrg

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

8. Nikhil619

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

9. Peter14

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

10. Nikhil619

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

11. Nikhil619

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

12. Nikhil619

@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

13. shubhamsrg

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

14. Peter14

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

15. Nikhil619

Also...molarity equals

16. Peter14

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

17. Peter14

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

18. Nikhil619

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

19. Nikhil619

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

20. shubhamsrg

thats just the formula I wrote -_-

21. Nikhil619

so? what to do?

22. shubhamsrg

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

23. Nikhil619

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