Thanks sir you clear my All problems ❤️

[@Mukesh_BE_100]

Thank you very much sir 😊

[@RahimWardak-c9p]

❤❤❤Thanks sir for this lecture ❤❤❤

[@studywithsarasundusNatali]

Great❤

[@ibrahimafridi5921]

Really very impressive and conceptual

[@BioChemWala]

Thanks

[@TaibKhan-uc5ok]

Sir Is 12 prottons and 12 neutrons are in carbon 12 atom ?

[@BioChemWala]

No

[@Mukesh_BE_100]

6 proton and 6 neutron bro

[@SaroshKhattak-s5d]

Sir from which thing we can know it's percentage abundance of isotope

[@RandomChennal]

It will be given Because ye already malom keya hai chemistry walo ny

[@AmeerAli-vo8gi]

Good sir g 😊

[@BioChemWala]

Thanks

[@arshidullah7673]

Mashallah very nice air

[@BioChemWala]

Thanks

[@alyeeniftikhar7224]

MashaAllha ❤❤❤❤

[@BioChemWala]

Thanks

[@asmatshah1204]

sir cl ke sath - negative sign be he?

[@BioChemWala]

Ok

[@ahsansajid3151]

Thnk u so much sir mashallah

[@BioChemWala]

So nice of you

[@gulzamanofficial2133]

Good leakcher

[@ONLINELearning-hr2ku]

thank you vert much

[@BioChemWala]

Welcome

[@Khalidkhan-g5p3z]

Sir aap na to only two chapters parhaya hay ye Kya hoga

[@khansir-g4p]

Sir one confused I do not understand why Average atomic mass taking is nessary

[@BioChemWala]

Because there are isotopes are present of them in the nature that is why

[@SudaiskhanKhan-ns2hv]

because it is neccerary

[@shaddyboy811]

Sir lecture ia superb but the one problem is your voice is very low Try to put handfree near your mouth....

[@Muzamilasghar-qo3de]

😅😅

[@madihabutt6168]

Your voice is very slow other wise very informative vedeo keep it up

[@BioChemWala]

Bundle of thanks

[@namalkhan4593]

Please improve your quality of video ..overall video is not clear ...otherwise lecture is best

[@BioChemWala]

Try to watch in 360p or 480p format then I think there will be no issue.

[@khansir-g4p]

Second why divide by 100

[@BioChemWala]

Due to percentage

[@Chingu546]

Apne formula ghalat likha he

[@BioChemWala]

How

[@tanmaymahajan7505]

No sir correct formula
