The quantity of carbon tetrachloride, CCl₄ she will use to make her conversion is molar mass

Description of mole

The mole of a substance is related to it's mass and molar mass according to the following equation:

Mole = mass / molar mass

How to determine the mole of CCl₄

  • Mass of CCl₄ = 30 g
  • Molar mass of CCl₄ = 12 + (35.5×4) = 154 g/mol
  • Mole of CCl₄ =?

Mole = mass / molar mass

Mole of CCl₄ = 150 / 154

Mole of CCl₄ = 0.974 mole

Thus, we can see that the molar mass of CCl₄ is needed to obtain the number of mole.
