Thanks 😊 very much mam
thank you mam❤
Mam pls tell me
Find the mass in g, kg, amu, mg
1) 100 atoms of Fe
2) 0.1Na atoms of Al
3) Na/2 atoms of He
Thank you mam
👍👌
Thanks

Thnku mam for thiss❤❤❤
1/4 atoms kahaa se aaya mam
Thanku mam
Ma'am can you please 🙏🙏solve:-
How many hydrogen atoms are there in Urea?
Thinkyou mem
Mam apki handwriting bahut achi ha
in a simple way
tq ma,am
Tqsm mam...
Tnks mam
Thankyou mam ji
🐐
Thankuu...
1÷28 Mole of nitrogen gas contains how much atom ? How will we solve this
👍🏻

Tnqq mam .. wow 🔥❤️ ... Osm .. ur handwriting is lit 🔥❤️😍
Dear Palak, thank you so much 😊
Yaa
@@BandhanaSharma hii mam
Well explained dii!!
Happy chocolate day!🍫🍫
Dii pr hmari book me 3rd part ka ans 13 hai... 52/4=13
Aisa kyu???
Dear student, maine numbering galat kar di hogi. 52u me 13atoms aate hai. 😊
Thanks and wish u the same 😊
@@BandhanaSharma okay dii😊
Mam I'm preparing for Neet 2023 ,could you please give mei some advice or tips ,whats your statgy during neet preparation or something...... l hope aap reply karo ge 🥰
Dear student, if u r consistent for ur work. U ll easily crack neet. I always reply to my student’s doubts 😊
1. Make ur own notes. Dont mark on books. Try to write on copy.
2. Read ncert thoroughly and mark some imp. Tips on book.
3. Solve ncert problems and then ncert exemplar. Because ncert is reference book fo boards and all competitive exams.

Ma'am 6.011*10^23 molecules of SO3 me kitne atoms honge?
4* 6.011*10^23
Agar (He) ya (Ar) ke place per koi compound ho toh ? Like MgSO4
Dear student, write ur complete question. I ll solve it. 😊
Tq madam
Nice mam
Mam please different between gram atomic mass and gram molecular mass video
Tq
Eqallatuu😂😂
From where does the 1 mole came in denominator
Dear student, it is unitary method that u have done in class 8 or 9. Kindly watch the video carefully, I have explained each and everything.
The first question is in modern abc book 1st chapter example no 41😅
Mam hmne 52 u of he me no. Of mles nikal ke NA se multiply krke no. Of atoms kyu nhi
Kyu nhi nikale
Dear student, u means mass of 1 atom. 52 u kitne atoms ka mass hoga ye batana hai. No. Of Moles me 6.022 X 10^23 atoms hote hai.
Please tell me how many element present in 8g of oxygen2- and solution
Dear student, apka question galat hai. Because Oxygen is itself an element.
How to multiply 52 by 6.022
I love u mam😘😘😘
🤍🤍🤍thnks mam
Ma'am why 1/4 for the unit .....?
Dear student, it is unity method. So the value has been taken 1/4.
One point thirty three (1.33) oh common 😅🤣🤣🤣
Mam i'm from pakistan❤️🇵🇰 I really appreciate this effort of yours❤️ I just watched your video 2 hours before my entry test and it really helped me❤️❤️❤️✨✨✨ Thankyouuuu❤️
Dear student, thank u for ur kind and heart warming words.
mere padose h yea
bihar m rehta h
pakistan hn???????????????
Plz aap 11th class ki physics pdao
Ap boht acha pdate ho
..
Plz madam

@@BandhanaSharma 😍 tnx
7.8×10²³...Last answer ....Check it
Can't we directly apply no. Of particles by Avogadro's number to find no. Of atoms
Dear student, U can apply. This formula is also derived from unitary method.
@@BandhanaSharma thank you
miss..i have a doubt...maam..
no.of he atom is 2..right ?
then where did '4u of he = 1 atom ' came...is it '2u of he = 1 atom' ? or not...?
Dear student, atomic mass of 1 atom of He is 4amu or 4u.
tell me in a little short, i do not understand topic Plis 🙏🙏
Madam apki writing ✍️😲..
Itni achi h 😍🌹..
Meko to meri writing hi smj nhi ati😁
Dear student, Thank u for ur kind words.
MAM YOU EXPLATION WAS KEY AND MY CONCEPT WAS LOCKER
WHICH U HAVE OPENED
THANK U MAM❤️
Mam why 4u of he is taken because in the question 52u of He is given
Atomic mass unit (amu or u) of 1 helium atom is 4u. You have to find how many atoms are there in 52u.
Agar each of its type ka puche toh bhi kya same hi hga🤐🙄
Ye kese hua 3.13*10Power 2
Mam please calculate the ratio of atoms Bata dijiye
Dear student, kindly write the complete question.
Please solve.calculate the mass of one atom of calcium
Dear student, I ll upload by tomorrow 😊
Thank you
I love u mam🏝🏝
Mam give me insta id ...so that i can talk.with u...plzz🙏
Op
Mam why u use the same pen in every video but nice
Dear student, This is my fav. Pen 😊😊
Ma'am pls reply 🙏
