NAME: NO2 AND FIND ITS DENSITY WHEN PRESSURE IS 0.97 atm TEMPERATRE IS 35 DEGREES C

IF PV = gmRT/mw THEN gm/V = gm/liter

finally put your answer in gm/ml

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

Ithink carbon dioxide, i am not completely sure.tell me if i am wrong.
