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

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

1. Identify Element Counts

Read CuCO3 and list how many atoms of each element are present:

  1. 1 atom of Copper (Cu)
  2. 1 atom of Carbon (C)
  3. 3 atoms of Oxygen (O)

2. Determine Atomic Masses

Look up each element mass from the periodic table:

  1. Copper (Cu) ~= 63.546 g/mol
  2. Carbon (C) ~= 12.011 g/mol
  3. Oxygen (O) ~= 15.999 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
  • Carbon (C): 1 x 12.011 = 12.010 g/mol
  • Oxygen (O): 3 x 15.999 = 48.000 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 + 1 x 12.011 + 3 x 15.999)

Molar Mass = 63.550 + 12.010 + 48.000

Molar Mass = 123.550 g/mol

Final rounded value shown on this page: 123.55 g/mol.
