1. Count The Number of Each Atom. The first step to finding the molar mass of Sodium Sulfate is to count the number of each atom present in a single molecule using the chemical formula, Na2SO4: 2. Find Atomic Mass of Each Element.
Suppose you want percent sulfate, SO 4 2–, in sodium sulfate. The formula mass of sodium sulfate is 142.04 and of that total 32.06 + 64.00 = 96.06 is sulfate. Thus, 96.06 Sulfate: ───── x 100 = 67.63% SO 4 2– 142.04 Notice: this is the sum of the percents sulfur and oxygen: 22.57% S + 45.06% 0 = 67.63% SO 4 2–. We may say sodium ...

Sodium Sulfate | Na2SO4 or Na2O4S | CID 24436 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.
Percent concentration by mass is defined as the mass of solute divided by the total mass of the solution and multiplied by 100%. So, #c% = m_(solute)/(m_(solution)) * 100%#, where. #m_(solution) = m_(solvent) + m_(solute)# There are two ways to change a solution's concentration by mass. Adding more solute - making the solution more concentrated;
Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na 2 SO 4 as well as several related hydrates. All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product.
