Because of its affinity for water, anhydrous sodium sulfate is often used to dry hydrophobic solvents used in aqueous organic extractions. For example a water based sample is extracted for organic compounds using dichloromethane, or ethyl ether in a separatory funnel. The organic layer is passed through a buchner funnel holding anhydrous sodium sulfate, yielding dried solvent extract.
Anhydrous sodium sulfate is added to the organic solution to remove any remaining water. Water can interfere with subsequent reactions or analyses by diluting the organic solution or forming undesired byproducts. Anhydrous sodium sulfate is a drying agent that effectively absorbs water, leaving behind a dry organic solution suitable for further processing.
If you mean what percentage of sodium sulfate is Na, the answer is about 32.4. That's for the anhydrous material. It can also be hydrated. In Glauber's salt, for example, a molecule of Na2SO4 is associated with 10 molecules of water. %Na = 14.3.
Sodium sulfate is a good drying agent for purification because it is anhydrous (contains no water molecules), making it effective at removing water from organic compounds. It is also relatively inert, meaning it doesn't react with the compounds being dried. Additionally, sodium sulfate is easy to separate from the dried product by simple filtration.
Sodium sulfate, in its anhydrous form (meaning without water) is a white crystalline salt. Wikipedia has more information, and a link is provided.
Anhydrous sodium sulfate is used as a drying agent to remove microscopic amounts of dissolved water in a solvent. It works by chemically reacting with the water by forming its hydrate, which is insoluble preferably in the solvent in this case dichloromethane. This allows one to filter off the crystals containing the water that would otherwise have remained dissolved in the dcm.

Sodium sulfate anhydrous can absorb water.
Anhydrous sodium sulfate is used in experiments to dry organic solvents by removing residual water. It is a desiccant, meaning it has a strong affinity for water and can absorb any remaining moisture in the solvent, making it suitable for certain chemical reactions that are sensitive to water.
Sodium sulfate.
Anhydrous sodium sulfate is considered as a drying agent. It is used in expirements to remove water from a solution or during an expirement. hope this helps.
Anhydrous sodium sulphate is Na2SO4
41,1 g of sodium sulfate (Na2SO4, anhydrous) contain 10,455.10e23 atoms.
Anhydrous sodium sulfate is a desiccant, meaning it has a strong affinity for water. When added to a dichloromethane solution, the anhydrous sodium sulfate will absorb any water present, effectively removing it from the solution by forming a hydrated salt. The water-free dichloromethane can then be decanted or filtered off for further use.
One can determine if acetone is anhydrous by using a drying agent like magnesium sulfate or sodium sulfate. These drying agents will absorb any water present in the acetone, indicating if it is anhydrous or not.
To calculate the mass of anhydrous sodium sulfate needed, you first need to determine the total moles of Na+ required. In this case, 60 ml * 0.1 mmol/ml = 6 mmol of Na+. Anhydrous sodium sulfate has a molecular weight of 142.04 g/mol, so you will need 6 mmol * 142.04 g/mol = 852.24 mg or 0.85224 grams of anhydrous sodium sulfate to prepare the 60ml solution.

For example uranyl nitrate may exist as an anhydrous compound.
