The chart shows the amount of solute that fully dissolved when added to 500 ml of water:

\begin{tabular}{|l|l|}
\hline
Solution & Amount of Solute \\
\hline
[tex]$X$[/tex] & 10 g \\
\hline
[tex]$Y$[/tex] & 12 g \\
\hline
[tex]$Z$[/tex] & 8 g \\
\hline
\end{tabular}

Which ranks the solutions in order of greatest to least solubility?

A. [tex]$Y \rightarrow X \rightarrow Z$[/tex]

B. [tex]$X \rightarrow Y \rightarrow Z$[/tex]

C. [tex]$Z \rightarrow X \rightarrow Y$[/tex]

D. [tex]$Y \rightarrow Z \rightarrow X$[/tex]

To rank the solutions in order of greatest to least solubility, we need to compare the amounts of solute that fully dissolved for each solution.

From the given chart:
- Solution [tex]\( X \)[/tex] dissolves 10 grams of solute.
- Solution [tex]\( Y \)[/tex] dissolves 12 grams of solute.
- Solution [tex]\( Z \)[/tex] dissolves 8 grams of solute.

To determine which solution has the greatest solubility, we compare the grams of solute dissolved:

1. Solution [tex]\( Y \)[/tex] dissolves the most amount of solute, with 12 grams.
2. Solution [tex]\( X \)[/tex] dissolves the next highest amount, with 10 grams.
3. Solution [tex]\( Z \)[/tex] dissolves the smallest amount of solute, with 8 grams.

Thus, when we rank these solutions from greatest to least solubility, we get:
[tex]\( Y \rightarrow X \rightarrow Z \)[/tex].

Therefore, the correct answer is:

[tex]\[ Y \rightarrow X \rightarrow Z \][/tex]
