for an element, how does Avogadro's number connect the atomic and macroscopic scales?
A. it describes the number of grams in 1 mole of an element
B. it describes the number of atoms in 1 mole of an element
C. it describes the number of moles in 1 gram of an element
D. it describes the number of atoms in 1 gram of an element
B. it describes the number of atoms in 1 mole of an element
Avogadro's number is defined as the number of atoms, molecules, ions, or other particles in one mole of a substance, which is approximately 6.022 x 10^23. This connects the atomic and macroscopic scales by allowing us to relate the number of atoms in a sample to the macroscopic properties of that sample.
