If oxygen has a molar mass of 16.0 g/mole, carbon has a molar mass of 12.0 g/mole and hydrogen has a molar mass of 1.01 g/mole, how many moles of ethanol do I have, if I have a beaker containing 10.0 g of ethanol (C2H5OH)
The number of mole of ethanol present in the beaker is 0.217 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 C₂H₅OH From the question given above, the following data were obtained: Mass of C₂H₅OH = 10 g Molar mass of C₂H₅OH = (12×2) + (1.01×5) + 16 + 1.01 = 46.06 g/mol Mole of C₂H₅OH =?
Mole = mass / molar mass Mole of C₂H₅OH = 10 / 46.06 Mole of C₂H₅OH = 0.217 mole
