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.

Rayon is a versatile fiber. Rayon is chemically Cellulose. It is widely claimed to have the same comfort properties as natural fibers, although the drape and slipperiness of rayon textiles are often more like nylon. It can imitate the feel and texture of silk, wool, cotton and linen. The fibers are easily dyed in a wide range of colors.
