The difference between a student's experimental measurement of the density of sodium chloride and the known density of this compound reflects the accuracy of the student's result.
Salt, also known as sodium chloride, is an ionic substance with the chemical formula NaCl, which denotes a 1:1 ratio of the ions sodium and chloride. The molar weights of 39.34 g Na and 60.66 g Cl in 100 g of NaCl are 22.99 and 35.45 g/mol, respectively. For both seawater and the extracellular fluid of many multicellular organisms, sodium chloride is the salt that contributes most to the saltiness. Table salt is frequently used as a condiment and food preservative in its edible form. A significant source of the salt and chlorine molecules utilized as feedstocks for additional chemical synthesis, sodium chloride is employed in significant amounts in numerous industrial processes.
