atomic masses; molecular mass;

for the last, what is avagradro's number.

yes

1) atomic mass

2) molar mass
3) 6.02 x 10^23

Avogadro's number is a fundamental constant in chemistry and physics. It represents the number of atoms, molecules, or other particles present in one mole of a substance. Avogadro's number is approximately 6.022 × 10^23 particles per mole.

To determine the number of representative particles in a mole of any substance, you use Avogadro's number. This means that there are 6.022 × 10^23 atoms, molecules, or other particles in one mole of any given substance.
