The molar mass of Ethanol is:
grams

Answer 1

To calculate the molar mass of ethanol (C2H5OH), we can break it down into its constituent elements based on the formula:

- Carbon (C): 2 atoms × 12.01 g/mol = 24.02 g/mol
- Hydrogen (H): 6 atoms × 1.01 g/mol = 6.06 g/mol
- Oxygen (O): 1 atom × 16.00 g/mol = 16.00 g/mol

Now, we sum these values together:

\[
24.02 \, \text{g/mol (C)} + 6.06 \, \text{g/mol (H)} + 16.00 \, \text{g/mol (O)} = 46.08 \, \text{g/mol}
\]

The molar mass of Ethanol is: **46.08 grams**.
