A saturated solution of NaCl is formed by adding 500.g of NaCl to 0.500L of water. The excess solid NaCl is filtered from the solution, and after being dried in an oven, the mass was determined to be 346.8g. Required:
What is the solubility of NaCl?

4.96 mol/dm³

Explanation:

From the question,

Mass of NaCl that dissolved in 0.5L of water = 500-346.8 = 153.2 g.

Therefore, 145.2(1/0.5)g of NaCl will dissolve in 1 L of water

mass of NaCl that will dissolve in 1 L of water = 290.4 g/dm³

Molar mass of NaCl = 58.5 g/mol.

Solubility is the amount of substance in mol that will dissolve in 1 L or 1 dm³ Solution.

 solubility in (mol/dm³) = solubility in (g/dm³)/molar mass.

solubility in (mol/dm³) = 290.4/58.5

solubility in (mol/dm³) = 4.96 mol/dm³

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
