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 so

lution, and after being dried in an oven, the mass was determined to be 346.8g.

Answer:

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

Which answer choice lists the number and type of elements in a compound in the way that is close to their actual arrangement?
alexandr1967 [171]

The chemical formula of a compound express the atoms by which the molecule is formed and the ratio of the atoms in which they are combined.

The space filling model of a compound describe the electron density in the compound of each atom.

The ball and stick arrangement of a compound describe the way in which the molecules are present in three dimensions.

The structural formula state the number of atoms present in the molecule, the type of element or atom present in the molecule and the way in which they are arranged closely which is the bond.

Thus only the structural formula only will cover all the options as stated.
