The mixture of salt and sand is heterogenous and their physical properties can be used to separate it. To separate sand and NaCl it must be diluted with water then filtrated using filter paper. The residual water is full of dissolved NaCl since NaCl is water soluble. The NaCl can dissolve in water because of water’s emergent property; versatility as a solvent. Because water is polar, it can break apart other molecules until the molecules are bonded with water. To separate the soluble NaCl from the water a physical change must occur and the water must be heated and evaporated into vapor.
Mass was calculated with 2 decimal points because our scale recorded mass with 2 decimal points. Because the mass of the beaker was subtracted from the mass
