Well you should know the formula and valency of each element first,
Sodium
formula - Na
valency - +1
Oxide
formula - Oxygen - O
valency - (-2)
Since the charge of the compound has to be 0 (zero)
2 atoms of sodium (+2) are required to neutralize the effect of the one oxygen atom (-2) ----------- [2 + (-2) = 0]
Na2O

How many moles are in 7.94g of sodium oxide?
To find the number of moles in 7.94g of sodium oxide, you need to divide the given mass by the molar mass of sodium oxide, which is 62g/mol. 7.94g / 62g/mol = 0.128 moles of sodium oxide.
How many electrons in Sodium Oxide?
Sodium oxide has the chemical formula of Na2O. To find the number of electrons in this molecule, we first need to know the number of electrons for each of its constituent atoms. The number of electrons in a neutral sodium atom is 11 and the number of electrons in a neutral oxygen atom is 8. So, after doing some simple arithmetic, we find that sodium oxide has 2*11 + 1*8 = 30 electrons per molecule.
How many formula units are in 4.89 mil of sodium oxide?
To determine the number of formula units in 4.89 moles of sodium oxide, you need to first calculate the molar mass of sodium oxide (Na2O). The molar mass of Na2O is 61.98 g/mol. Next, you convert 4.89 moles to grams by multiplying by the molar mass. Finally, divide the mass by the molar mass of Na2O to find the number of formula units, which is approximately 4.34 x 10^23 formula units.
How many sodium ions there in 85g of sodium oxide Na2O?
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.
What Mass of sodium oxide formed when 6.9 grams sodium are heated in air?
To find the mass of sodium oxide formed, we first need to calculate the moles of sodium used, which is 0.3 moles (6.9g / 23g/mol). Since one mole of sodium reacts with one mole of oxygen to form sodium oxide, the moles of sodium oxide formed is also 0.3 moles. The molar mass of sodium oxide (Na2O) is 62g/mol. Therefore, the mass of sodium oxide formed is 18.6 grams (0.3 moles * 62g/mol).

What is the molecular formula for sodium chlorate?
You'll find that NaClO2 is the formula for sodium chlorite.
How many sodium ions there in 85g of sodium oxide Na2O?
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.
What information does the chemical formula for a compound provide about the submicroscopic structure of the compound?
The chemical formula of a compound provides information about the types and numbers of atoms present in a molecule. It gives insight into the elements involved in the compound and the ratios in which they are combined, but it does not provide specific details about the arrangement or bonding between the atoms.

Where can you find sodium chloride and iron oxide at home?
Sodium ChorideSodium chloride [NaCl] is salt.You would find it at home in the kitchen.Iron OxideIron oxide [Fe2O3] is rust.You would find it at home anywhere that iron has rusted.
What is the chemical formula for sodium aluminum sulfate?
You will find that AlNa(SO4)2 is the formula for sodium aluminum sulfate. That's its anhydrous form (no water). You usually see it written AlNa(SO4)2 + 12 H2O to include the water that it likes to hang out with.
How do you find the chemical formula for iron III oxide?
To find the chemical formula for iron (III) oxide, recognize that iron is in the +3 oxidation state and oxygen is in the -2 oxidation state. The chemical formula for iron (III) oxide is Fe2O3, as two iron atoms have a total oxidation state of +6 (2*+3) and three oxygen atoms have a total oxidation state of -6 (3*-2), balancing out the charges.
