Answer:
[tex]m_{undissolved}=27g[/tex]
Explanation:
Hello there!
In this case, according to the given information of the solubility of copper chloride, as the maximum amount of this salt one can dissolve without having a precipitate, we infer that since just 73 grams are actually dissolved, the following amount will remain solid as a precipitate:
[tex]m_{undissolved}=100g-73g\\\\m_{undissolved}=27g[/tex]
Best regards!
