20:43 convert pascal into bar
23:21 weight by weight percent question
29:53 non volatile solute means i(vant hoff factor) = 1 as alpha will be zero
33:15 if not given take dissociation or association 100 percent means alpha =1 therefore i=n n = 2 in case of agbr
42:51 taking ethanol as solvent as freezing point depression constant is always defined for solvent
44:59 i=1 as ethanol is non polar solvent
46:03 henry law question
50:19 both liquid and gaseous phase question
56:13 no info given about i so take i = 1

03:00 If Density of Solvent 1 then molality = molarity
15:00 Moles of KCl = Moles of AgNO3
1:37:00 Conversion
1:43:21 Practice

[supercuber]

HARDEST PART IS NOT THE QUESTIONS BUT THE STUPIDLY LENGTHY CALCULATIONS.

[imnikhi]

For question 2 you can find molality by by the no of moles of agno3 because it is acting as solute
1Molar =1 mole in 1000mL
1/1000mole=1mL
1/50 mole = 20 mL
Moles of Agno3 is 0.02
Now mass of KCl is 25 g
Now you can find molality
👉No.of moles of Agno3/mass of KCl (in kg )
Which is 4/5
And after multiply
i×kf×molality
2×2×4/5=3.2( near to 3)
👆 Answer

vapour phase liquid phase 50:34
pascal into bar 20:46
17:10
55:08 i value
1:41:00 alcohol i = 1

SIR DONE... DID 80% QUESTIONS BY MYSELF.. FEELING CONFIDENT NOW💖🔥🖤🧡

[dhanrajroat]

One of the best techer of physical chemistry 🎉❤❤

[aryanpanwar]

Being an NDA aspirant, I answered 80% questions correctly!! All thanks to Alakh Pandey sir for his indomitable 5-year-old superb lectures ...

[Productivityx]

1 bar== 1atm or 1atm= 1.01325 bar
1 atm= 1.013*10^5 Pa
Percentage of dissociation/100 = alpha
In freezing point formula, molality of solute mein nich solvent's mass not solute jiska ∆Tf nikal rhe
1atm=10^5 Pa
i for glucose sucrose alcohol urea =1
X = moles in liq phase
Y= moles in vapour phase

[RAJANMANDAL]

कौन कौन मानता है कि राहुल सर एक महान शिक्षक है।🙏🙏🙏🙏🙏🙏

[Bgmiofficial]

i think u are going to be the next famous teacher on yt

[omkumar]

summary points of solution
11:28 equation
45:50 solvent ka hi depresion const define hota ha isliye ethanol solvent ha = mass of solvent is 50 not 48.2
1:16:08 calculation redooo
1:26:00 pa ma pucha ha to bar ko 10^5 sa multiply krna ha
1:35:25 approximations
1:38:15 dekho ques ky pucha ha
redo the above ques and try hw ques
best of luck for 2 nd attemt

Sir mein yes no bolta hoon par aapko pata kaise chalega 😁😁😁😁😁❤️❤️❤️

At 1:05:53 why did we take 1.5 as vol of acetic acid instead of 1.2 ml??
