Densityis defined as themass per unit volume. Chapter 6 Flashcards | Quizlet Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. Thus, 48 g of Mg is equivalent to $12.04 \times {10^{23}}$ atoms. Incidentally, Avogadro first introduced his gas theory in 1811, and it was ignored for 50 years. Example: How many atoms are present in 32.80 grams of copper? This means that the atom of oxygen has a mass that is, \[\dfrac{16\, \cancel{u}}{12\, \cancel{u}} = \dfrac{4}{3} 1.33 \nonumber\]. 2 or three. Look up the sample's atomic weight on a periodic table of the elements. We also need a bridge between these numbers, which we are unable to measure directly, and the weights of substances, which we do measure and observe. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 1023 atoms The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
