What is the molar mass of Sodium, Water & Sodium Chloride?
[Relative atomic mass: H = 1; O = 16; Na = 23; Cl = 35.5]
Molar mass of Sodium = Relative atomic mass of Na = 23 g mol-1
Molar mass of Water = Relative molecular mass of H2O = 1 + 1 + 16 = 18 g mol-1
Molar mass of Sodium Chloride = Relative formula mass of NaCl = 23 + 35.5 = 58.5 g mol-1
Note: Sodium is a metal made up of only Na atoms; Water is a molecular compound made up of H2O molecules; Sodium Chloride is an ionic compound made up of NaCl formula units.
