Final answer:

The formula mass of copper(II) fluoride (CuF₂) is calculated by adding the atomic mass of copper (63.55 amu) to twice the atomic mass of fluorine (2 × 19.00 amu), resulting in a formula mass of 101.55 amu.

Step-by-step explanation:

The formula mass of copper(II) fluoride (CuF₂) can be calculated by adding the atomic mass of copper (Cu) with twice the atomic mass of fluorine (F). Using the given atomic masses, the calculation is as follows:

Cu: 1 × 63.55 amu = 63.55 amu
F: 2 × 19.00 amu = 38.00 amu
Total formula mass of CuF₂ = 63.55 amu + 38.00 amu = 101.55 amu

Therefore, the formula mass of copper(II) fluoride is 101.55 amu.
