0.34 moles Na2O (1 mole O 2-/1 mole Na2O)(6.022 X 1023/1 mole O 2-)
2.1 X 1023 ions of oxygen
================
The number of sodium ions is 16,518.10e23.
All sodium atoms, whether or not they are ions have 11 protons.
The formula mass of sodium oxide, Na2O is 2(23.0)+16.0 = 62.0 Amount of sodium oxide = 7.94/62.0 = 0.128mol
There are two moles of sodium ions in two moles of sodium chloride.
46 grams of sodium is 2 moles. 2 mol of sodium forms 1 mol of sodium oxide. So it makes 62 g of sodium oxide.
The number of sodium ions is 16,518.10e23.
3.33 x 10^23 sodium ions
2 Sodium and Chloride.
iron(II) oxide is FeO and has two ions Fe2+ and O2-
Two Na plus ions will combine with an O2- to form the basic compound sodium oxide. When water is further added, the neutral salt, sodium hydroxide is formed.
Since the formula shows two sodium atoms in each formula unit of sodium sulfate and this compound normally completely ionizes in water solution, the number of sodium ions will be twice the number of moles of the salt; in this instance, 1.0 moles of sodium ions.
Na2O or sodium oxide is an ionic compound.The formula mass of Na2O is 2(23.0) + 16 = 62.0 Amount of Na2O = 6.2/62.0 = 0.1mol In each formula unit of Na2O there are two singly positively charged Na+ ions. So, amount of sodium ions = 0.2 moles.
All sodium atoms, whether or not they are ions have 11 protons.
