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
Answer: The water cycle shows the continuous movement of water within the Earth and atmosphere. ... Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).
