Question

Calculate the molar mass of sulfur.

Answer 1

1. The molar mass of a substance is defined as the mass of 1 mole of the given substance.
2. Sulphur ${\mathrm{S}}_8$ exists in two states rhombic sulphur and monoclinic sulphur.
3. The molar mass of a substance is calculated by summing all masses of atoms involved in a molecule.
4. The atomic mass of sulphur is 32 u.
5. The molar mass of rhombic sulphur ${\mathrm{S}}_8$ $=32\times 8$

$=256\mathrm{g}$

The molar mass of sulphur in rhombic form is (S₈) 256g.
