Thank you so much.You explained the calculations splendidly.

Very nicely explained Madam. Thank you very much. Kindly explain for 1 N HCL

Great job. Thank you so much

Thnk you very much for explaining explicitly

Thank you so much for the video

Gajab yaar. Thanks

Khub khub abhar 🙏🙏🙏🙏🙏❤️

Just what I needed 🙏l have been looking for this explanation to solve these exact question for the past 3days

Thanks dear... 💝💝 from Bangladesh

Thank you so much ma'am.

thanks for your help

Good explanation

best explanation ever

Nice teaching

Very Nice

Good method

Thank u so much

Thank you

Great video, thank you. I want to prepare a 100 ml 25% v/v glutaraldehyde solution and the glutaraldehyde available is 50% wt% glutaraldehyde in water, MW= 100.12 g/mol, d= 1.106 g/ml. Would I be correct for using C1V1= C2V2. The answer I get is 50 ml of 50% glutaraldehyde in 100 ml to give 25% v/v glutaraldehyde. Thanks

Thank you very much for your kind Explanation

Nice

For the video at 0:51, it was said that molecular weight is 36.5 g/mL. But it's not correct, because molecular weight is measured at g/mole.

Yes you age correct 36.5g/mole.

And also when calculating V, I don’t understand how we ended up with ml while density is in g/m^3 and mass is in grams

Thanx ma'am

Thank you😊

Thank you mam

Please correct the formula I think there is some mistake in it..with the first calculation the molarity can be calculated correctly..but the formula in the second case does not give the correct molarity

How to prepare 0.5 M sucrose solution, 0.15M KCL Plz tell mee mam

Awosome

Molecular weight = gram / mole you can write gram/ ML is not correct.🙏

+Sagar Patel Yes you r right👍

For 100% = 30.9 x100/37 But for 37% = 30.9 ml.... Why it Should not be 37%=30.9x37

Mole concept is so tough. I die 😭

Suppose I have pH of 9.8 of distilled water . How much HCL ( % assay is say 37 ) is to be added to bring down to 6.8 or even 7.0 pH . volume of water say 2000 ml ? Kindly explain

How to check given HCl is 37%

Again the same problem mam, I didn't get how we can write the 83.5mL will provide the 1M HCl?

Mam plz tell me M/20 HCl in 250 ml kitna chahiye hcl

mam.. mere liye ek boht bada doubt he ..plz solve it .. agr me 6g sugar aur 10g sodium chloride ko mixx kr k ek powder bana leta hu aur usme se muje 0.40mol required he to woh quantity kitne gram ki hogi!!!!

good explanation....

Excellent job maam but i don't understand how to prepare 0.1M HCl in 250 ml from 100% stock solution of HCl Because according to my calculations Answer is 7.7

Ek video 1% HCl ke liye bhi bnaye mam thank you.

how can we know that 0.1M HCL for 250ml is 2.09ml??????.. reply must

Root canal Perpetual annoyance

Maam 100 ml of 0.08M how much ml I have to put in the beaker it's urgent please help me

Please tel me how to prepare 7M HCL

Why are we calculating for 100% when we use 37% HCl?

Who have a problem in that types of questions

Mam with this formula can we can calculate normal solution also

+amol kadam yes, use equivalent weight instead of molecular weight to calculate normality.

How 37% is taken into calculation...what if we have 36% Hcl ....the volume will be the same ....then 36% of 1M HCl will have 30.9mL

Y 100 kun lkha h.... dissolve to 1000 m krna h

6M HCL?

100% hcl means 83.5 ml in 100 ml madem

how is the 83.5 mL considered related to 1M?

Mol. Wt. Unit is g/mol

molecular weight in g per mole not per ml of hcl

The specific gravity of sulfuric acid(H2SO4 ) is 1.31. What is its density? Show the complete solution?

Hold hold .... You are confusing us

So you can do 0.5, 0.02.... you are doing easy calculations yourself...

Bloody registers

Exagerrated video 👎

Itna confuss kar dia simoe bat ka

Thanks alot

Great

Thank you
