I2 is called as molecular iodine
This is a trick question because "I2" is the chemical symbol for MOLECULAR iodine (your question did not say melt Iodine, it said melt I2).Only gaseous iodine is composed of I2 molecules and as it is a gas it CAN NOT melt.
The atomic mass of I is 127. The atomic mass of F is 19. Therefore the molecular mass of the compound is 127+5x19=214u.

A "vapor" in chemistry is always the gas phase of a substance that is more familiar in one of its condensed phases: liquid or solid. Therefore, iodine vapor is the gas phase of the element iodine, and has the same molecular composition as the solid, I2. Iodine is a solid at standard temperature and pressure, but sublimes directly to gas phase, without any intermediate liquid phase, at only moderately higher temperatures than the standard.
