Is AMU the unit for both 'atomic mass' and 'molecular mass'?

Click For Summary
SUMMARY

The atomic mass unit (AMU) serves as a unit of mass applicable to both atomic and molecular mass measurements. While it was primarily designed for atoms, such as hydrogen with a mass of approximately 1 u and carbon at about 12 u, it can also be utilized to express molecular mass. Therefore, AMU is versatile enough to represent the mass of compounds by summing the atomic masses of constituent elements.

PREREQUISITES

Well, an atomic mass unit is a unit of mass, so you can use it to represent anything. You could even say "My car weighs <insert large number here> atomic mass units".

It was designed for atoms though, e.g. hydrogen has a mass of ~1 u, carbon has a mass of ~12 u, etc. If you combine those, you could use it for molecular mass too.
