Answer:

Well...#V=(nRT)/P#..I get approx. #3*L#

Explanation:

And so #P=(100*kPa)/(101.3*kPa*atm^-1)#...I use atmospheres instead of #kPa# because I think the units are more accessible...

#V=((3.65*g)/(32.00*g*mol^-1)xx0.0821*(L*atm)/(K*mol)xx273.15*K)/((100*kPa)/(101.3*kPa*atm^-1))#

#=??*L#

Note that you must simply KNOW that oxygen is diatomic...in fact all the elemental gases with any chemistry are diatomic...
