gaseous state
The density of a substantce at 1 atm pressure and 773K is 0.4g/lit. If the molecular weight of the substance is 30 the forces existing among the molecules are repulsive or attractive.
Acc to my calculations compressibility factor turns out to be less than 1 thus forces should be attractive. Answer is repulsive tho, someone pls explain

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.If compressibility factor (z) < 1 then Vreal must be less than Videal
If V real is less than v ideal then the gas particles must be attracting each other rather than repelling as repelling would essentially mean particles are going further away . Therefore attraction force is greater
Attaching my calc below
O m g
Just revised my calc
Turns out z>1
Sorry for the trouble ðŸ˜
