Finally, use the given mass of sodium oxide and the molar mass of sodium chloride to calculate the mass of sodium chloride produced.
What is the correct chemical equation for the following mass percent of oxygen in sodium oxide?
The chemical formula for sodium oxide is Na2O. To determine the mass percent of oxygen in Na2O, we need to calculate the molar mass of oxygen (O) and sodium oxide (Na2O), then use these values to calculate the mass percent of oxygen in Na2O.
What is the percentage of oxygen in sodium oxide?
The percentage of oxygen in sodium oxide is 72.7% as the chemical formula for sodium oxide is Na2O, which contains 2 oxygen atoms and 1 sodium atom. To calculate the percentage of oxygen, you divide the molar mass of oxygen by the molar mass of sodium oxide and multiply by 100.
What is the mass for sodium oxide plus water?
The mass of sodium oxide plus water would be the sum of the masses of sodium oxide and water individually. Sodium oxide has a molar mass of 62 g/mol and water has a molar mass of 18 g/mol. By knowing the amount of each substance, you can calculate the total mass.
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.
What mass of sodium is needed to produce 108.2 g of sodium oxide?
To calculate the mass of sodium needed to produce 108.2 g of sodium oxide, you need to determine the molar mass ratio between sodium and sodium oxide.

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).
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.
What is the molar mass of oxide?
The molar mass of an oxide depends on the specific compound you are referring to, as different oxides have different compositions. To calculate the molar mass of an oxide, you would need to add up the atomic masses of all the elements present in the compound according to their stoichiometric ratios.
What mass in grams of ethylene oxide is needed to react with 10 g of water?
To calculate the mass of ethylene oxide needed to react with 10 g of water, you need to determine the molar ratio of water to ethylene oxide in the balanced chemical equation for the reaction. Once you have the molar ratio, you can use it to calculate the mass of ethylene oxide needed. The molar mass of ethylene oxide is 44.05 g/mol.
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.
