Question

a solution is to be prepared with a sodium ion concentration of 0.555 mol/l. what mass of sodium sulfate (g) is needed to prepare 2.00 liters of such a solution?

Answer 1

Mass of sodium sulfate (g) is needed to prepare 2.00 liters of such a solution is  78.122.

Sodium Sulfate $=N a_2 \mathrm{So}_4 .$

$[\mathrm{Na}+]=0.555 \mathrm{mo} / / \mathrm{L}$

$\mathrm{mol} \mathrm{Nat}=0.555 \times2 =1.11 \mathrm{~mol}$

mol $\mathrm{Nu}_2 \mathrm{Su}_4=\frac{1.11}{2}=0.55 \mathrm{~mol} .$

mol $\mathrm{Na}_2 \mathrm{So}_4=m_0 \times m \omega$ = 0.55 *142.04=78.122.

Drying organic liquids uses sodium sulphate. in powdered household laundry detergents as a filler. to eliminate minute air bubbles from molten glass as a fining agent. The decahydrate form of Glauber's salt is used as a laxative to eliminate medicines like acetaminophen from the body. The inorganic substance sodium sulfate and numerous related hydrates have the formula Na2SO4. White solids in all of their forms, they are very soluble in water. The decahydrate is a significant commodity chemical product, with a 6 million tonne yearly production.
