Claim: Sound is not matter. Which piece of evidence supports this claim? Sound is made of atoms and has a specific density.
Sound is created when molecules vibrate in a medium,
Sound takes up space and can be weighed on a scale.
Sound does not have mass or volume, it is a form of energy.

Sound Energy is a form of Mechanical Energy

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.
