Correct answer: C) 1.6 g
Molarity is the moles of solute present per liter solution.
The given molarity of the solution is 0.01 M.
Volume of the solution = 1 L
Calculating the moles from molarity and volume:

Converting moles to mass of copper sulfate:

This interaction must be one of the intermolecular forces, particularly, Van der Waals forces. From the description given, this force is called <em>induced dipole-induced dipole forces</em>. Dipole is defined as the separation of positive and negative charges. This type of intermolecular force is very weak compared to hydrogen bonding.
Wave velocity refers to speed, but can also be speed and direction.
Answer:
100 ml = 0.1 L
I divided 100 by 1000 because 1000ml = 1L
