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.
I2 is called as molecular iodine
lF5
The molecular formula for iodine pentafluoride is IF5. No prefix in front of iodine is understood to be one, but mono- is not used for the first element in a binary covalent compount. The prefix penta- means five, so the subscript for fluoride is 5. Unfortunately, there is no way to write the 5 as a subscript.
Atomic mass of Iodine is 126.90447 ± 0.00003 u.
You need to know the Relative Molecular Mass of the compound, then you find the ratio of that compared to the R.M.M. of I2O5 and then multiply the ratio by I2O5. That should be it.
The iodine pentafluoride (IF5) is a molecular compound.
IF5
The name of this compound is iodine heptafluoride.
Iodine pentafluoride, IF5, is a fluoride of iodine. It is a colourless or yellow liquid with a density of 3250 kg m−3. It was first synthesized by Henri Moissan in 1891 by burning solid iodine in fluorine gas.[3] This exothermic reaction is still used to produce iodine pentafluoride, although the reaction conditions have been improved.[4][5] An alternative IUPAC name is pentafluoro-λ5-iodane.

Square pyramidal
yes because it has one lone pair in the central atom

I2
gram-Equivalent of iodine is 127 because its molecular weight is 2(127) and 2 electron change involve in the redox titration
