Explanation:
The number of mole of ethanol, CH₃CH₂OH the chemist will use in the experiment is 0.65 mole
<h3>Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation:
Mole = mass / molar mass
<h3>How to determine the mole of CH₃CH₂OH</h3>
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 = mass / molar mass
Mole of CH₃CH₂OH = 30 / 46
Mole of CH₃CH₂OH = 0.65 mole
