Write the formulae for Sodium chloride and calculate the molecular mass for Sodium chloride.

Open in App

Solution

The formula of Ethanol is $NaCl$
Molecular mass of a substance is defined as the sum of masses of atoms or elements present in the molecule.
So the atomic mass of $NaCl$ - Atomic mass of $Na$ +Atomic mass of $Cl$
$= 23 + 35.5 = 58.5 u$
