The mass number of an atom is representative of the number of protons and neutrons. Calculate the number of protons from the mass number and neutrons. 100 = x + 56 44=x. Aluminium has the density of 2.70 g/cm^3. How many moles of aluminium are in a. Aluminium-27 atom is the stable isotope of aluminium with relative atomic mass 26.98153 and nuclear spin (5)/2. A metallic element that has the atomic number 13, atomic symbol Al, and atomic weight 26.98. Youtube music converter free download for mac. Medical Subject Headings (MeSH). Since there is '2' moles of Aluminium per mole of Al 2 O 3 you multiplly the number of moles calculated for aluminum oxide by 2. Number of Al 2 O 3 molecules in 5 x 10-3 mole = (6.032 x 10 23)x( 5 x 10-3) = 30.115 x 10 20. Number of aluminum ions per molecule = 2. Number of aluminum ions in mole Al 2 O 3 =30.115 x 10 20 x 2 = 60.23 x 10 20. Aluminium or aluminum (13 Al) has 22 known isotopes from 22 Al to 43 Al and 4 known isomers.Only 27 Al (stable isotope) and 26 Al (radioactive isotope, t 1/2 = 7.2 × 10 5 y) occur naturally, however 27 Al comprises nearly all natural aluminium.
