Mam agar weight of air required kaise calculate kare same question me?
Thank you.
Best explanation 😀
Mam hindi me hi samjha dete
Can you please explain the aspect of nitrogen for dry product being 77/100,why
We are considering that air contains oxygen and nitrogen and other constituents as negligible. By mass, air contains approx. 23 % oxygen and 77% nitrogen To find out nitrogen , we calculate 77% of air. It Means 77/100 of air
Thanks a lot Ma'am!!! Thanks to you, my exam was so good today, Can't express how grateful I am to Saraswati Mata and you !!!
Thanks a lot ma'am!!! Your videos really helped me out.I can't thank You enough!!!
Thanks a lot ma'am!!! It was really easy to understand this whole topics through this video. Can't thank you enough!!!
Lot of thanks to you madam

dhanyawaad mam
Thank you so much mam... ❤❤❤❤❤🎉🎉🎉🎉🎉
Thanks a lot!!! Your video really helped me in my exam today
mam aap to hamare external aaye the in git
Worst!She just read the lecture sheet, didn’t explain anything.This is not the right way of teaching.
Thank you for the feedback and thanks for watching the video
Hi. What do you think about the combustion of green methanol "CH30H"? The amount of CO2 obtained in the combustion is similar to natural gas. It seems that the only advantage is to be able to transport the green H2 combined with CO2. Then in the end the CO2 emissions are similar to burning LNG. Thank you.
Easy to understand explanation. Great video 💯
Ma am you are good teacher I understand easily please uplod more videos
Suggest topics that you require
Helpful in2023
Nyc explanation mam year 2023❤😂
❤❤ thnku mam
muje class mai kuch samjh nahi aa rara tha par ye video dekh kar sab aa gaya
i am watching this video just 6 hours before exam really your videos are very helpful
Tqq mam ❤
Thanq mam🎉
What is 100/21 means? Thanks
There is approx. 21% oxygen in the air. So For calculating amount of air for combustion, we must multiply the total oxygen used for combustion with 100/21
@@avyuktnair yes 21 for volume and 23 for weight.. Thanks bro!
Mam hinglish me padaya karo
Plz tell me name of this process
Can i get pdf
Nice maam something i understood now
tq mam
Thank you mam❤
Tq mam ... Nice explanation
Thank you so much ma'am because after searching so many video i found your video & it was very useful for me
Purity%/100 hota hai ma'am
It would be great and helpful if you provided the PPTs you are using to teach, nice lesson thank you 👍
Thanks for this clear and concise video. It came in handy.
Very nice
omg what a pathetic way of teaching
Hind me Sam jhaiye
Mam please add other videos
Ma'am please try in hindi english both languages
Good concept
Mem water litr me diya h to use mili litr me bdlna pdga ...
Ma'am, is this also the soda lime galss?
Thnx mam ☺️
Sach kahe to mam college me 10 din class krne ke baad apka video ke baad smjh me aaay
I have read your book your book is awesome
Thankyou mam
