Atomic mass unit is equivalent to _ the mass of carbon isotope C-12
Correct answer: B. 1/12th
- A. 12 times
- B. 1/12th
- C. 1/6th
- D. 6 times
Explanation
The atomic mass unit (AMU or amu) of an element is a measure of its atomic mass. Also known as the dalton (Da) or unified atomic mass unit (u), the AMU expresses both atomic masses and molecular masses. AMU is defined as one-twelfth the mass of an atom of carbon-12 (12C). masses. 1 amu is equal to 1.67377 x 10-24 grams or 1.67377 x 10-27 kilograms

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
