Jul 17, 2025
Hey there! As a supplier of Sodium Acetate 3H2O, I often get asked about its molar mass. So, let's dive right into it and break down what the molar mass of Sodium Acetate 3H2O actually is.
First off, let's understand what Sodium Acetate 3H2O is. It's a trihydrate form of sodium acetate, which means it has three water molecules attached to each unit of sodium acetate. Chemically, it's pretty interesting stuff and has a bunch of uses in different industries.
To figure out the molar mass, we need to know the molar masses of the individual elements that make up Sodium Acetate 3H2O. The chemical formula for Sodium Acetate 3H2O is Formula:C2H3NaO2.3H2O. This tells us exactly what elements are present and in what quantities.
Let's start with carbon (C). The molar mass of carbon is approximately 12.01 g/mol. In the formula, we have 2 carbon atoms. So, the total mass contributed by carbon is 2 * 12.01 = 24.02 g/mol.
Next up is hydrogen (H). The molar mass of hydrogen is about 1.01 g/mol. In the formula, we have a total of 3 hydrogen atoms from the acetate part and 6 hydrogen atoms from the three water molecules, so that's 3 + 6 = 9 hydrogen atoms in total. The mass contributed by hydrogen is 9 * 1.01 = 9.09 g/mol.
Sodium (Na) has a molar mass of around 22.99 g/mol. There's only 1 sodium atom in the formula, so it contributes 22.99 g/mol to the total molar mass.
Oxygen (O) has a molar mass of about 16.00 g/mol. We have 2 oxygen atoms from the acetate part and 3 oxygen atoms from the three water molecules, so that's 2 + 3 = 5 oxygen atoms. The mass contributed by oxygen is 5 * 16.00 = 80.00 g/mol.
Now, to find the molar mass of Sodium Acetate 3H2O, we just add up the masses contributed by each element: 24.02 + 9.09 + 22.99 + 80.00 = 136.10 g/mol. So, the molar mass of Sodium Acetate 3H2O is approximately 136.10 g/mol.
Why is knowing the molar mass important? Well, it's crucial in a lot of chemical calculations. For example, if you're in a lab and you need to prepare a specific concentration of a solution using Sodium Acetate 3H2O, the molar mass helps you figure out how much of the compound you need to weigh out.
In the industrial world, Technical Grade Sodium Acetate is widely used. It's used in things like textile dyeing, as a buffering agent in the food industry, and even in some heating pads. The molar mass plays a role here too, as it helps in quality control and ensuring the right proportions are used in different processes.
Another important piece of information about Sodium Acetate 3H2O is its CAS NO:6131-90-4. The CAS number is like a unique identifier for the compound. It's used by chemists, researchers, and regulatory bodies to accurately refer to Sodium Acetate 3H2O in various databases and documents.
