Mass of Copper metal dissolved = 0.1090 g

Moles of Copper dissolved = 0.1090 g * \frac{1 mol}{63.55 g} = 0.00172 mol Cu

Total volume of the solution = 203.1 mL * \frac{1 L}{1000 mL} = 0.2031 L

Calculating the molarity of copper ions in the solution:

Molarity of a solution = \frac{Moles of solute}{Volume of solution (L)}

= \frac{0.00172 mol Cu^{2+}}{0.2031 L}

=0.00845 mol/L

Therefore the molarity of copper ions is 0.00845 mol/L

Answer: Option (c) is the correct answer.

Explanation:

In liquids, molecules are held by slightly less strong intermolecular forces of attraction as compared to solids.

Hence, molecules of a liquid are able to slide past each other as they have more kinetic energy than the molecules of a solid.

As a result, liquids are able to occupy the shape of container in which they are placed. Also, liquids have fixed volume but no fixed shape.

Thus, we can conclude that liquids have a variable shape and a fixed volume.

6. Explain why there is no base unit for the dimension of volume.
weqwewe [10]
Because in SI, the expectation is that area and volume will be expressed in terms of a linear dimension( the metre) or its multiples.
