Sodium Chloride has a density of 2.17 g/cm3
Explanation:
-The resultant crystal is likely to be of Potassium Chloride
-The silvery metal is likely Potassium due to it's similar melting point of 63.5 °C which when reacts with Chlorine gas form a Potassium chloride with the following properties:
Hence, the crystal formed is not Sodium Chloride.
-The properties of sodium chloride are:
