Dissolve some NaCl in water and add it up to 250 mL.
Water can dissolve NaCl because it has polar molecular structure which allows it to interact with the ions in NaCl, breaking the ionic bonds. Ethanol is a polar molecule as well, making it able to dissolve NaCl through similar polar interactions. Ethanol can also dissolve in water due to its polar characteristics and ability to form hydrogen bonds with water molecules.
NaCl dissolve in water
Some are soluble (NaCl), some are insoluble (AgCl).
1 mole NaCl = 58.44g NaCl0.48mol NaCl x 58.44g NaCl/1mol NaCl = 28g NaCl
Elements that have some characteristics of a metal and some characteristics of a nonmetal are called semimetals or metalloids.

NaCl, or sodium chloride, exhibits several key mineral characteristics. It has a crystalline structure, typically forming cubic crystals, and is soluble in water. NaCl is also characterized by its distinctive salty taste and is commonly found in nature as the mineral halite. Additionally, it has a relatively low hardness on the Mohs scale, typically rated at 2.5 to 3.
1. NaCl is the chemical formula (more correct formula unit) of sodium chloride. 2. Sodium chloride exist as a natural mineral: halite (NaCl with some imputities).
I'm going to assume that you mean 23.34g of NaCl. 1 mole NaCl = 58.442g NaCl (the atomic weight of Na and Cl in grams) 23.34g NaCl x (1mol NaCl/58.442g NaCl) = 0.3994mol NaCl
1 mole NaCl = 58.443g NaCl = 6.022 x 1023 formula units NaCl 3.6g NaCl x 1mol NaCl/58.443g NaCl x 6.022 x 1023 formula units NaCl/mol NaCl = 3.7 x 1022 formula units NaCl
