Snow forms in the upper atmosphere in a cold aid mass that is supersatuated with water vapor. When the snow later falls through a lower, warm air mass, rain forms. When atomic weight is 63.5 amu. Calculate the edge length of the unit cell.

To calculate the edge length of the unit cell, we need to use the concept of atomic weight and Avogadro's number. Here's how you can calculate it step by step:

1. Determine the molar mass: Since the atomic weight given is measured in atomic mass units (amu), we need to convert it to grams per mole (g/mol) by multiplying it by the molar mass constant (1 g/mol). In this case, the atomic weight is 63.5 amu, so the molar mass is 63.5 g/mol.

2. Calculate the number of atoms in one mole: Avogadro's number (6.022 x 10^23 atoms/mol) represents the number of atoms in one mole of a substance. It allows us to convert between the mass of a substance and the number of atoms or molecules.

3. Determine the number of atoms in a unit cell: For a simple cubic crystal lattice, there is one atom per unit cell.

4. Calculate the edge length of the unit cell: The edge length (a) of the unit cell can be determined using the following relationship:
- a = [V / (n^(1/3))] , where a is the edge length, V is the molar volume, and n is the number of atoms in the unit cell.

5. Calculate the molar volume: To calculate the molar volume (V), we use the formula:
- V = (molar mass / number of atoms in a unit cell) x Avogadro's number.

Now, let's plug in the values and calculate the edge length (a) of the unit cell:

1. Molar mass = 63.5 g/mol
2. Number of atoms in a unit cell = 1
3. Avogadro's number = 6.022 x 10^23 atoms/mol

Calculating the molar volume (V):
V = (molar mass / number of atoms in a unit cell) x Avogadro's number
V = (63.5 g/mol / 1) x (6.022 x 10^23 atoms/mol)
V = 3.823 x 10^24 g

Calculating the edge length (a):
a = [V / (n^(1/3))]
a = [3.823 x 10^24 g / (1^(1/3))]
a = [3.823 x 10^24 g / 1]
a = 3.823 x 10^24 g

Therefore, the edge length of the unit cell is 3.823 x 10^24 g.
