Because water is polar and oil is nonpolar, their molecules are not
attracted to each other. The molecules of a polar solvent like water are
attracted to other polar molecules, such as those of sugar. This explains
why sugar has such a high solubility in water. Ionic compounds, such
as sodium chloride, are also highly soluble in water. Because water
molecules are polar, they interact with the sodium and chloride ions.
In general, polar solvents dissolve polar solutes, and nonpolar solvents
dissolve nonpolar solutes. This concept is often expressed as “Like
dissolves like.”
So many substances dissolve in water that it is sometimes called
the universal solvent. Water is considered to be essential for life
because it can carry just about anything the body needs to take in
or needs to get rid of.
Mass fraction has been the mass of an individual element with respect to the compound. The mass fraction of chloride in calcium chlorate is 0.171.
<h3>What is meant by a mass fraction?</h3>
Mass fraction has been defined as the ratio of the masses of the individual elements present in a compound to the total mass of the molecule or compound.
The formula for a mass fraction (w) is given as,
Mass fraction (w) = mass ÷ total mass
Given,
Mass of chlorine = 35.453 grams per mole
The molar mass of calcium chlorate (Ca(ClO₃)₂) = 206.98 grams per mole
Substituting and solving the values above as
w = mass of chlorine ÷ total mass of calcium chlorate
w = 35.453 ÷ 206.98
w = 0.171
Therefore, the mass fraction of Cl in calcium chlorate is 0.171.
