Introduction

In the world of chemistry, understanding the concept of ethanol molar mass holds significant importance. This article delves into the depths of this crucial aspect, exploring its relevance, applications, and implications in various fields.

Identify the Chemical Formula: Ethanol’s chemical formula is C2H5OH.

Determine the Atomic Masses: Look up the atomic masses of each element in the periodic table.

• Carbon (C): 12.01 atomic mass units (amu)
• Hydrogen (H): 1.01 amu
• Oxygen (O): 16.00 amu

Count the Number of Atoms: Count how many atoms of each element are present in one molecule of ethanol.

• Carbon (C): 2 atoms
• Hydrogen (H): 6 atoms
• Oxygen (O): 1 atom

Calculate the Contribution of Each Element to the Total Molar Mass: Multiply the number of atoms of each element by its atomic mass.

• Carbon (C): 2 atoms x 12.01 amu = 24.02 amu
• Hydrogen (H): 6 atoms x 1.01 amu = 6.06 amu
• Oxygen (O): 1 atom x 16.00 amu = 16.00 amu

Sum the Contributions: Add up the contributions from all elements to find the total molar mass.

• Total molar mass = 24.02 amu (carbon) + 6.06 amu (hydrogen) + 16.00 amu (oxygen) = 46.07 amu

So, the molar mass of ethanol (C2H5OH) is approximately 46.07 grams per mole (g/mol).
