There are 2 Na atoms in the reactant side of the equation 2NaN3(s) → 3Na(s). Each unit of NaN3 contains 1 Na atom, and there are 2 units of NaN3, resulting in a total of 2 Na atoms.
1 mole Na = 6.022 x 1023 atoms Na 0.200 mole Na x (6.022 x 1023 atoms/1 mole Na) = 1.20 x 1023 atoms Na
6NaCl contains 6 atoms of sodium (Na) and 6 atoms of chlorine (Cl), totaling 12 atoms in total.
There are a total of 16 atoms in the formula 2Na2SO4. This includes 4 Na atoms, 2 S atoms, and 8 O atoms.
there are 5 atoms (1Na 1Cl and 3O) and they are all elements.
There are two sodium atoms in each molecule of Na2O, as indicated by the subscript immediately after the symbol for sodium atoms in the formula.
6 atoms only
6.22 x 1023 atoms
6 Na means 6 atoms of Sodium 6 Na means 6 atoms of Sodium
0.125 moles x 6.02x10^23 atoms/mole = 7.53x10^22 atoms

1 mole Na = 6.022 x 1023 atoms Na 0.200 mole Na x (6.022 x 1023 atoms/1 mole Na) = 1.20 x 1023 atoms Na
3.5 grams Na (1 mole Na/22.99 grams)(6.022 X 1023/1 mole Na) = 9.2 X 1022 atoms of sodium ===================
1, because Na does not have a number after it.
