Question
The molar mass of ethanol (C₂H₅OH) is approximately:
Correct Answer
Option B is the correct answer.
Detailed Explanation
Ethanol formula is C₂H₆O. Molar mass = (2×12.01) + (6×1.008) + 16.00 = 24.02 + 6.048 + 16.00 = 46.068 g/mol, approximately 46.07 g/mol.
Hint
Add the atomic masses for two carbons, six hydrogens, and one oxygen.
