What Is The Molar Mass Of Sucrose (C12H22O11) ?
p; (Molecular Weight)
Molecular compounds consist of a large collection of molecules.
The molar mass (or molecular weight) of a molecular compound
is defined in the following way:
Molar Mass = Mass
of 1 mole of molecules
Therefore, to grasp the molar mass of a molecular compound we
need simply determine the molar mass of molecules. For sucrose
(table sugar) we have the molecular formula C12H22O11 and the
molar mass would be
p;mass of sucrose
p;= 12x12.011 g + 22x31.008
p;g + 11x15.999g
p;= 342.3 g
Or, we would say that the molar mass of sucrose = 342.3 g/mol
(i.e., a mole of sucrose molecules have a mass of 342.3 g)
