The question here is solved using basic chemistry. CaCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of CaCl2 that dissolves.
CaCl2(s) --> Ca+(aq) + 2 Cl⁻(aq)
            [Cl⁻] = 0.65 mol CaCl2/1L × 2 mol Cl⁻ / 1 mol CaCl2 = 1.3 M
The answer to this question is [Cl⁻] = 1.3 M

Varvara68 [4.7K]
A voltaic cell spontaneously converts chemical energy to electrical energy. The correct option among all the options given in the question is option "2". Actually voltaic cell is an electrochemical cell that converts the chemical contained within it by the process of chemical reaction to produce electrical energy. The voltaic cell contains an anode and a cathode. Anode is an electrode where the oxidation occurs and cathode is the electrode where reduction occurs. The oxidation and the reduction part occurs in two separate parts of the cell known as half-cell.

The volume of the granite as
Trava [24]

The volume of the granite as determined by water displacement is 9.35 mL. This value in cm³ is 9.35cm³.

<h3>How to calculate volume in cm³?</h3>

The conversion factor of mL and cm³ is given as follows: 1 mL = 1 cm³

According to this question, the volume of the granite as determined by water displacement is 9.35 mL.

This value in cm³ can be converted as follows:

9.35mL × 1 = 9.35cm³

Therefore, the volume of the granite as determined by water displacement is 9.35 mL. This value in cm³ is 9.35cm³.
