이상기체방정식. PV = WRT / M

 

 

What is the molecular mass (in amu) of a gaseous element if 1.44 g occupies 1.60 L at 8657.51 torr and 37.8 °C?

 

---------------------------------------------------

 

PV = nRT

PV = WRT / M

( 식 설명 https://ywpop.tistory.com/8198 )

 

 

M = WRT / PV

= [(1.44) (0.08206) (273.15+37.8)] / [(8657.51/760) (1.60)]

= 2.02 g/mol

 

 

: 2.02
