Stp me temperature 25 c NAHI hota??? To phir kelvin me 298 ho ga?? Kindly guide
Because K = °C + 273K (ye formula book mein hain pg . 48)
Unhon ne ye kiya hai, K = 25°C + 273K = 298K
25°C is standard temperature for solutions (Liquids)etc...

Great lecture ❤
Sir numerical ka elawa AP chemistry I theory bi smjatay ha
You are first lecturerar whom i subscribed🫶🏻
Sir Q no 19 ma87.9 jo Molar Mass nikala ha wo Strontium ya Yttrium gas ka ha
sir reply to Kara 😇
Sir you are great thanks alot ♥️♥️ ♥️
The test will conduct on tommorow your lecture is very helpful 😊😮 but their is a little bit confusion in numerical no 18 calculation 😢😢
I think you must try it again my dear
Sir book mein density kg /dm3 me kahi gayi ha but our answer is in kg/m3 why?
?????????
PL give ans me of my question
Thanks😊
You can change it in kg/dm3 as well
Is it necessary to write R's value in the term of specialized arranged units like first atm than any other
Yes
Thanks sir for brilliant lecture😊
Sir
G
values ka ratta marna zaroori hai mujhe yaad ho gaeen hai sari values
Sir
G
mein nai oxygen and hydrogen wala part kar liya hai
Good ma sha Allah
i like u are teaching method sir
Sir question no 17 ka Ans thek nhi a raha calculation sa
Mara bi ni a raha h
Sir kindly ya bata da ka exercise ch 3 ma question 19 ka answer hum na gram per mole ma ku Liya kg ma ku nhi
g/mol mien hi molar mass find karty ham
Aoa young sir
Sir mujha naw wo values ko shift karna nhi samjh ata for example AP na 18 numerical ka andar karwaya hai
Mien samjha deta hun aap ko
But ap Koshish karien video ko dobara daikhien
@MWSChemistry sir dekha hai Lekin phir nhi ayi samjh
Or sir alhumdullia mana ya chapter bhi nhi kiya abhi tak direct excerise ko samjh Rahi hu 😂🙂
Sirr g you are really great ❤❤
sir realy your teaching methode is so nice and amazing hum easily understand kar sakty han
❣️
Sir yaa molecular weight ni mil rhaa hy kindly bataa daaa
Ye ana bhi ni😍
Sir calculate kesy krna hy? Jo ap 2 values likhty = daal k!!! 😭??? Pls bta den....!!!! Humny usy rearrange krna hy?
Try it again
