Answer:
46.06
Explanation:
The molar mass of ethanol (C2H5OH) can be calculated by finding the sum of the atomic masses of each element multiplied by the number of atoms in the molecule.
From the provided table:
* Carbon (C) has a molar mass of 12.01 g/mol
* Hydrogen (H) has a molar mass of 1.01 g/mol
* Oxygen (O) has a molar mass of 16.00 g/mol
In a molecule of ethanol (C2H5OH), there are:
* 2 carbon atoms
* 6 hydrogen atoms
* 1 oxygen atom
Therefore, the molar mass of ethanol is:
(2 x 12.01 g/mol) + (6 x 1.01 g/mol) + (1 x 16.00 g/mol) = 46.06 g/mol
So the answer is 46.06.
