You know that one molecule of nitrogen gas, #"N"_color(blue)(2)#, contains two atoms of nitrogen, #color(blue)(2) xx "N"#. Now, a mole is simply a very, very large collection of particles. In order to have one mole of things, let's say particles, you need to have #6.022 * 10^(23)# particles #-># this is known as Avogadro's constant and acts as the definition of the mole . 2020-02-07 · How to Calculate the Number of Atoms in a Sample Step 1: Find the Molar Mass of the Formula Find a periodic table of elements to find the molar mass of your sample. If Step 2: Find the Number of Moles The example is 32.80 grams of Cu. Change that into moles using the molar mass you found Step Number of atoms of N = Number of moles × Avogadro's constant. = 0.4 mol × 6.022 × 10 23 atoms/mol.

2019-08-09 · It is believed 74% of the mass of the Milky Way, for example, is in the form of hydrogen atoms. The Sun contains approximately 10 57 atoms of hydrogen. If you multiply the number of atoms per star (10 57) times the estimated number of stars in the universe (10 23), you get a value of 10 80 atoms in the known universe.
