Question

complete the sentences to explain the difference between atomic mass and molar mass. average atomic mass is a weighted average of all isotopes of an element. average atomic mass is measured in atomic mass units (amu). this is an extremely small unit that is not very useful to scientists. instead, scientists use molar mass, which is the atomic mass in grams per mole. one mole of an element is 6.02×10²³ representative particles.

Explanation:

Average atomic mass is a weighted - average of an element's isotopes and is measured in atomic mass units (amu). Atomic mass unit is a very small unit not practical for lab use. Molar mass is the atomic mass in grams per mole. Scientists use molar mass because it relates to the number of representative particles (6.02×10²³) in a mole of an element.

Answer:

Average atomic mass is a weighted average of all isotopes of an element, measured in atomic mass units (amu). Atomic mass unit is an extremely small unit not very useful to scientists. Instead, scientists use molar mass, which is the atomic mass in grams per mole. One mole of an element is 6.02×10²³ representative particles.
