2:37 Law of chemical combination
10:49 Atomic Mass
19:03 Mole concept
Sir volume of 1 mole of gas at 273K and 1 atm (STP) is 22.4 L. 22.7 L is for 1 mole of gas at 273K and 1 Bar. 🙌
correct
New STP conditions 1bar and 273K
21:54 sir 22.7 nhi 22.4 hona chaiye
Real 22.7 Hota hai par hum 9th se 22.4 padhte lekin accurate 22.7 Hota I hope it helps 🙂
Shi bola
22.4 ------>NTP Wale case mein
22.7------->STP Wale case mein
22.7 In real life but for JEE we consider 22.4 21:45
No, It depends on pressure in STP. If 1 bar then 22.7 and if 1atm then 22.4
I think this is the best series for mid terms exams
the fact u dont have formality and normality, along with ppm and ppb, makes it a greater burden
guys who are agree with me that we want only our rahul dudi sir in physical as well as inorganin chemistry
I agree
As well as organic chemistry also

22.7 hi hota hai bhaii
When STP IS 1 Bar T is 273K molar volume is 22.7 L
When STP is 1 atm T is 273K molar volume is 22.4 L
Hope it helps......
Sir to moles when volume at sto is given I think formula is n=volume/22.4 pls check once
Same doubt
When STP IS 1 Bar T is 273K molar volume is 22.7 L
When STP is 1 atm T is 273K molar volume is 22.4 L
Hope it cleared your doubt.......
