this the H2O answer​

Answer 1

Atomic mass and molecular mass:

• The average mass of an element's atoms, expressed in atomic mass units (amu, commonly known as daltons, D), is the element's atomic mass. The mass of each isotope is multiplied by its abundance to produce the atomic mass, which is a weighted average of all the isotopes of that element. (Atomic mass is also known as atomic weight, however "mass" is a more precise phrase.) The atomic mass of an element, measured in amu, is equal to the mass in grammes of one mole of an element. This relationship between the atomic mass and the mole concept is important in chemistry.
• The mass of a given molecule is its molecular mass (m), which is expressed in daltons (Da or u). Because they contain various isotopes of an element, multiple molecules of the same substance can have distinct molecular weights. According to IUPAC, the related quantity relative molecular mass is a unitless comparison between the mass of a molecule and the unified atomic mass unit (also called the dalton). The molar mass is unrelated to, but distinct from, the molecular mass and relative molecular mass. The molar mass, which is stated in g/mol, is defined as the mass of a specific material divided by the amount of a substance. As a result, the molar mass represents the average of several molecules or particles.
