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
================
To determine the number of sodium ions in 85g of sodium oxide (Na2O), first calculate the molar mass of Na2O. This can be done by adding the atomic masses of sodium (Na) and oxygen (O) in the compound. Then, find the number of moles of Na2O in 85g using the molar mass. Since Na2O contains 2 sodium ions per formula unit, multiply the number of moles by 2 to find the number of sodium ions.
There are two elements, namely sodium and oxygen.
Potassium oxide, with the chemical formula K2O, consists of two potassium ions (K+) and one oxide ion (O2-). Therefore, there are a total of 3 ions in potassium oxide.
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
Sodium oxide is made up of three atoms: two sodium atoms and one oxygen atom.

In a NaCl (sodium chloride) solution, there are two types of ions present: sodium ions (Na+) and chloride ions (Cl-). This is because when NaCl dissolves in water, it dissociates into these two ions, which are responsible for conducting electricity in the solution.
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.
There are two elements, namely sodium and oxygen.

Potassium oxide, with the chemical formula K2O, consists of two potassium ions (K+) and one oxide ion (O2-). Therefore, there are a total of 3 ions in potassium oxide.
There are 0.850 moles of Na2SO4 in 325 mL of 0.850 M solution. Since Na2SO4 contains 2 sodium ions per formula unit, there will be 2*0.850 moles of sodium ions in the solution. Thus, there are 1.7 moles of sodium ions in 325 mL of 0.850 M Na2SO4 solution.
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
three sodium ions
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.
Sodium oxide is made up of three atoms: two sodium atoms and one oxygen atom.
