CoachTo calculate the molar mass of sodium oxide (Na2O), you would add the atomic masses of sodium (Na) and oxygen (O) together. The Atomic Mass of sodium is 22.99 g/mol (from the Periodic Table) and oxygen is 16.00 g/mol. Therefore, the molar mass of sodium oxide is 2*(22.99) + 16.00 = 61.98 g/mol.

Calcuate the mass of sodium chloride produced if 12.3 g of sodium oxide reacts with an excess of calcium chloride?
To calculate the mass of sodium chloride produced, first balance the chemical equation for the reaction between sodium oxide and calcium chloride. Next, determine the molar ratio between sodium oxide and sodium chloride in the balanced equation. 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 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 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 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.
