The mass and density of salt depend on whether you're talking about table salt (NaCl) or sea salt.

Here's a breakdown:

Table Salt (NaCl)

* Mass: The mass of a specific amount of table salt is determined by how much you have. It's measured in grams or kilograms. For example, a teaspoon of table salt has a mass of approximately 5 grams.

* Density: The density of table salt is approximately 2.16 g/cm³ (grams per cubic centimeter) at room temperature. This means that 1 cubic centimeter of table salt has a mass of 2.16 grams.

Sea Salt

* Mass: Similar to table salt, the mass of sea salt depends on the quantity you're measuring.

* Density: Sea salt has a slightly lower density than table salt, typically around 2.1 g/cm³. This is because sea salt contains other minerals besides sodium chloride (NaCl), which can affect its density.

Key Point: The density of salt can also be affected by its crystal structure and humidity.
