but maam at stp the temperature is 0 degree celsius, which is freezing point of water....and water no longer remains gas at that temperature and this formula is only applicable for gases
Because H20 is also available in gas form and yah at stp par poochh rha hain aur stp par volume 22.4L hota
nice explaination
Thanks for liking
