The number of mole of ethanol, CH₃CH₂OH the chemist will use in the experiment is 0.65 mole

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 CH₃CH₂OH

From the question given above, the following data were obtained:

  • Mass of CH₃CH₂OH = 30 g
  • Molar mass of CH₃CH₂OH = 12 + (1×3) + 12 + (1×2) + 16 + 1 = 46 g/mol
  • Mole of CH₃CH₂OH =?

Mole = mass / molar mass

Mole of CH₃CH₂OH = 30 / 46

Mole of CH₃CH₂OH = 0.65 mole
