1.	When 3.2 g S is vaporized at 450^(@)C and 723 mm pressure, the vapours occupy a volume of 780 mL What is the molecular formula of S vapours ?
Answer» SOLUTION :GIVEN, P =2 atm, T=270=273=543 K `w_(CO_(2))=2xx1.53g,m_(CO_(2))=44` `because PV=(w//m)RT` `2xxV=[(2xx1.53)//44]xx0.0821xx543` `THEREFORE V=1.55` litre
