JAMB Chemistry 2024 EP 142 - Calculations In Solubility + Likely Exam Questions

[@OforkansiChibuikem]

Sir I just love your humor while teaching 😂😂

[@peaceudochukwuanwasi2494]

Yes the last question is Pb(NO3)2

[@Somtochukwuoti]

When you solved it did you get any answer in the option?

[@bestloveihejirika-dd6em]

Thank you so much for, your 03school It has really helped me to improve

[@FavourChiamaka-kj7us]

Amen 🙏

[@RitaAkubo]

Amen Sir

[@jamesjatau5486]

Amen

[@idowuopemipo1376]

For the last question, lead(II)trioxoitrate(v) is Pb(NO3)2 instead of PbNO3 that you used. The right answer should be 0.50mol/dm3. Option C

[@mmesomafelix3236]

you are right, even the second to the last question's answer was wrong

[@adeitantomide3921]

The option c was 0.5g which is still wrong. The correct option is still D. Although the compound formula was incorrect

[@WinnerAnayo]

Sir in 2014/ 15 question the mistake Pb ( NO3)2 is from the molar mass caculation 331g not 269.
Thank you for the teaching it helps alot

[@o3schools1]

Thanks guys
Please use the correct mass and formula
Clear and obvious mistake

[@ArthurDigitals]

Soft and easy to adhere a bih accolades to you sir 🎉😄😄🎉😄😄

[@Chizaram.]

Thank you sir

[@ChiomaIfeanacho]

Thank you so much

[@peaceudochukwuanwasi2494]

I enjoy this teaching 😊😊

[@EvelynAnelechi]

You to good

[@godwinmarvellous]

It's really a good app

[@Demilade-mn4ib]

Can't lie man be better than my school teacher, if you know what I mean

[@mosesizuora-ut8gh]

Love this❤

[@WinifredHalim-pt1pg]

Sir lead(ii) trioxonitrate(v)is pb(No3)2 so the molar mass is 331g/mol

[@theyyluvvsoibi]

Amen oo😊

[@PraiseChisom-n1e]

Amen oo🎉

[@QUEENOKOGBUO]

Amen oo🙏

[@PaulEgbayelo-q2r]

Amen 🙏 Thank you sir❤

[@rejoicegabriella2365]

Amen oooo

[@OforahChiamaka-em4ew]

sir pls do jamb give the molar mass of an element in other years

[@FidelisUbah]

Yes we need the solubility under graphing

[@abdurrazakSikirullahih]

Good job sir! For the last question , Lead II trioxonitrate V is Pb(NO3)2.

[@o3schools1]

Thanks
We already spotted that
Check through the comments

[@GiftnmesomaChukwuemeka]

Amen 😅
This is indeed an interesting class.

[@Raihana-f1b]

Amen sir

[@anthonianora__399]

Thank you so much
I understand it now
I'm greatfull 🙏🏾

[@FaruqAjibola]

Ameen

[@nwanerichizor6252]

Thank you so much sir ❤

[@RidwanullahOlawale]

Thank you sir ❤❤

[@demirth_digitals]

Amen❤❤❤

[@Pearls-qq5cm]

The answer of the last question is 0.5
The symbol for the compound is Pb(NO3)2

[@o3schools1]

Thanks

We already spotted that

[@HappyChristopher-ru1wq]

Amen🎉

[@HikmatAkanbi]

Sir there is answer in that last question.The answer is 0.50g

[@o3schools1]

The Pb(NO3)2 was the catch there and they caught a whole master T. Chai ☕️

[@o3schools1]

Thanks for providing the answer dear soldier

[@HikmatAkanbi]

You are welcome

[@gracesesi5949]

amen

[@peretimichristopher9424]

How do you get such compound formula?? Like the KNO3

[@mercy-ibe]

1994 question 19 , the one of kno3 , the volume was in gdm3 why did you still add 100 to the formula

[@DavidOgbetuo]

Sir please u didn't touch solubility graph and it comes out a lot 😢😢😢

[@mondaydorcas3612]

Sir why did u not approximate for the last one from 0.65 to 1??

[@o3schools1]

The distance is too far

[@edosogriki7821]

Sir solubility graphs please

[@AdegokeTaofeek-zu2ck]

Why we can't convert the last question when is 0.615 why it can't be 1.00

[@blessingihuoma9339]

Sir, in the last question solved, I mean the 2014/15 questions, I thought the correct option would be option B by approximating the 0.615 to 1.00g...?
Please i was confused at that

[@o3schools1]

The distance is too far . And they didn’t ask you to approximate in the question

[@mondaydorcas3612]

Ok

[@OforkansiChibuikem]

Sir I thought that lead ii trioxonitrate v is represented with pb2NO3?

[@o3schools1]

No

[@ComfortAma-nz2pn]

Sir please is it the same as wassce

[@anthonianora__399]

Amen oooooooo 🙏🏾🙏🏾

[@ubongbassey578]

Iam little bit confused when u still use include 1000 in d solubility formula that was asked to find solubility in mol per dm3. In 1994>19.because u said when solubility is given in mol per dm3 u don't include 1000 in d formula, except in cm3

[@o3schools1]

No sir
We said when Volume is given in dm3 , you don’t include the 1000 in the formula but when volume is given in cm3 you can

[@HikmatAkanbi]

😮amen

[@Ifyhel]

Amen o

[@georgenwaokolobia5080]

Last question is not none of the above .
Pb(NO3)2
That’s the chemical formula for
Lead ii trioxonitrate( v )

[@GiftnmesomaChukwuemeka]

Sir, u made mistake in the molecular formula of the compound, it should be Pb(NO3)2
The answer should be C

[@o3schools1]

Yes Thanks we already spotted that
Look through the comments

[@nwanerichizor6252]

Sir please you made a mistake, previously you said solubility in cm3. Is mX1000 all over w X v ,then you change it to 1000m all over w X v

[@obiano7studio411]

Amen ❤😂

[@OforahChiamaka-em4ew]

amenooo

[@georginaaluola]

Amen sir 😊

[@JacksonOkon-wt9cs]

Amenoo

[@elizabethjoseph2830]

Sir the answer to the last question is wrong, it's supposed to be answer C.You got the formula wrong that's why the answer is not there.
Pb(NO3)2
