Given that Na-23 is the only natural isotope of sodium,what is the mass of one Na atom and the mass of Avogadro's number of Na atoms,respectively?

Question

Quizplus · Accepted Answer

The mass of one Na-23 atom is 22.99 amu (atomic mass units), which is the same as the atomic mass of Na-23. Avogadro's number is the number of atoms in one mole of a substance, which is 6.022 x 10^23. Therefore, the mass of Avogadro's number of Na-23 atoms is 22.99 g (grams), which is obtained by multiplying the atomic mass by Avogadro's number and converting from amu to grams using the molar mass constant (1 g/mol).
