Bond order is proportional to the bond length is a False statement since Bond order is inversely proportional to the bond length.

The process which involves absorption of heat is endothermic.

Here given all the options are involving in absorption of heat. Hence, all the above are endithermic.

To get the mass of a mole of NaCl, we need to add the molar atomic weights of the individual elements i.e, Na and Cl

Atomic weights of Na = 22.99 gm/mol  Cl = 35.45 gm/mol

Now, mass of a mole of NaCl = 22.99 + 35.45 = 58.44 gm/mol.
