Can 1750 mL of water dissolve 4.6 moles of copper sulfate CuSO4

No

Explanation:

We first find the solubility of the copper sulphate salt

Number of moles = 4.6 moles

Volume = 1.75 L

Molarity = number of moles / volume = 4.6/1.75 = 2.6 molL-1

Hence, only 2.6 moles of Copper II sulphate dissolves in 1.75L of water. Hence 4.6 moles of copper II Sulphate dies not dissolve in 1.75 L of water.
