Calculation of the Number of Layers in Calcium Chloride Formation

To determine the number of layers in a calcium chloride formation with a mass of 6.3 kg, we need to use the molar mass of calcium chloride and the Avogadro's number.

The molar mass of calcium chloride (CaCl2) can be calculated by adding the atomic masses of calcium (Ca) and chlorine (Cl). The atomic mass of calcium is approximately 40.08 g/mol, and the atomic mass of chlorine is approximately 35.45 g/mol.

The molar mass of calcium chloride (CaCl2) is therefore: 1 calcium atom (Ca) = 40.08 g/mol 2 chlorine atoms (2Cl) = 2 * 35.45 g/mol = 70.90 g/mol

Total molar mass of calcium chloride (CaCl2) = 40.08 g/mol + 70.90 g/mol = 111.98 g/mol

Now, we can calculate the number of moles of calcium chloride using the given mass of 6.3 kg (or 6300 g) and the molar mass of calcium chloride:

Number of moles of calcium chloride = Mass of calcium chloride / Molar mass of calcium chloride Number of moles of calcium chloride = 6300 g / 111.98 g/mol

Let's calculate the number of moles of calcium chloride:

Number of moles of calcium chloride = 6300 g / 111.98 g/mol = 56.25 mol

Since each mole of calcium chloride contains one formula unit, we can say that the number of layers in the calcium chloride formation is equal to the number of moles of calcium chloride.

Therefore, the calcium chloride formation with a mass of 6.3 kg contains approximately 56.25 layers.

Please note that the calculation assumes that the calcium chloride formation is a perfect crystal structure with each layer consisting of one formula unit of calcium chloride. In reality, the structure may be more complex, and the number of layers may vary depending on the specific arrangement of the calcium chloride molecules.
