Calculate the molecular mass of menthol, C₁₀H₂₀O.

Question

Quizplus · Accepted Answer

To calculate the molecular mass of menthol, we need to add up the atomic masses of all the atoms in its chemical formula. The molecular formula of menthol is C₁₀H₂₀O, which contains 10 carbon atoms (C), 20 hydrogen atoms (H), 2 oxygen atoms (O), and 2 sulfur atoms (S). The atomic masses of these atoms are: C: 12.01 amu H: 1.01 amu O: 16.00 amu S: 32.07 amu Therefore, the molecular mass of menthol is: (10 × 12.01 amu) + (20 × 1.01 amu) + (2 × 16.00 amu) + (2 × 32.07 amu) = 156.26 amu Thus, the best choice is A) 156.26 amu.
