XII-2 #16, Relative Lowering Of Vapour Pressure - Practice Problems

[@aayushmaanmalik1630]

Mam pls show the proper derivation of relative lowering of vapor pressure 🙏

[@andrewjustin256]

@18:50 Ms. Seema, I have obtained a different answer; mine answer is 0.25 × 40 or 10g while yours is 0.2 × 40g. Could you please enlighten me what appears to be happening here?

[@rpuraaaaab]

The answer to 2.18 which we calculated is slightly wrong in comparison to that given in NCERT. Ma'am, if we do not exclude the value of n2 in the calculation, we get the answer as 10 g.

thank you mam!!! I hope you are well :)

[@abishekk.s.277]

I have a doubt mam in the last problem(ex:2.6) we have neglected n2, but in this video, in the first problem(intext 2.9) we are not neglecting n2. On what basis it is done mam.................Plz help me out

[@user-be3kk8mb1v]

Because in that question mass of solute was 0.5 g. Here the solute is 50g

Thanks seema

[@hudagal6471]

How does the mole fraction of the solute become 1??

[@vikky5867]

Because it is the one molal solution

[@vikky5867]

Molal solution means one mole of solute present in 1000g of solvent

[@akshatashesh1125]
