`X`-rays diffraction studies show that copper crystallizes in an fcc unit cell with cell edge of `3.608 xx 10^(-8) cm`. In a separte experiment, copper is determined to have a density of `8.92 g cm^(3)`. Calculate the atomic mass of copper.

Explanation

To calculate the atomic mass of copper based on the given information, we can follow these steps:

### Step 1: Identify the given data
- Cell edge length (a) = \(3.608 \times 10^{-8} \, \text{cm}\)
- Density (D) = \(8.92 \, \text{g/cm}^3\)
- For an FCC unit cell, the number of atoms per unit cell (Z) = 4

### Step 2: Use the formula for density
