Best ResponseYou've already chosen the best response.1a) Formula for \(\sf C_xN_y\) \(\sf PV=nRT=\dfrac{mRT}{M}\) \(\sf M_{C_xN_y}=\dfrac{mRT}{PV}=\dfrac{1.05~g*(62.36367~L~torr~K^{1}mol^{1})*298.15~K }{751~torr*0.5~L}=51.99~g/mol \) \(\sf M_{C_xN_y}\approx 52~g/mol=x~12~g/mol+y~14~g/mol\) Trial and error gives \(\sf C_2N_2\) The structure is probably dw:1439562426305:dw The structure does not have a permanent dipole moment because of symmetry  individual dipole moments caused by the lone pairs on the N terminal atoms cancel each other out.
