Computing Molar Mass of Copper(II) Fluoride Step by Step

Molar Mass of Copper(II) Fluoride: Step-by-Step Calculation

1. Identify Element Counts

Read CuF2 and list how many atoms of each element are present:

  1. 1 atom of Copper (Cu)
  2. 2 atoms of Fluorine (F)

2. Determine Atomic Masses

Look up each element mass from the periodic table:

  1. Copper (Cu) ~= 63.546 g/mol
  2. Fluorine (F) ~= 18.998 g/mol

3. Multiply Atomic Mass by Quantity

Multiply atom count by atomic mass for each element:

  • Copper (Cu): 1 x 63.546 = 63.550 g/mol
  • Fluorine (F): 2 x 18.998 = 38.000 g/mol

4. Sum Total Molar Mass

Add all contributions to get the final molar mass in g/mol.

Molar Mass = (1 x 63.546 + 2 x 18.998)

Molar Mass = 63.550 + 38.000

Molar Mass = 101.540 g/mol

Final rounded value shown on this page: 101.54 g/mol.
