What is the molar mass of CuO?

To calculate the molar mass of copper(II) oxide (CuO), you need to sum the atomic masses of copper (Cu) and oxygen (O). The atomic masses can be found on the periodic table of elements, and they are usually reported in atomic mass units (amu) or grams per mole (g/mol).

Here are the steps to calculate the molar mass of CuO:

1. Identify the Atomic Mass of Copper (Cu):
Look up the atomic mass of copper on the periodic table. The atomic mass of copper is approximately 63.55 g/mol.

2. Identify the Atomic Mass of Oxygen (O):
Look up the atomic mass of oxygen on the periodic table. The atomic mass of oxygen is approximately 16.00 g/mol.

3. Write the Chemical Formula of Copper(II) Oxide:
The chemical formula for copper(II) oxide is CuO, which indicates that there is one atom of copper and one atom of oxygen in each molecule.

4. Calculate the Molar Mass of CuO:
Add the atomic mass of copper to the atomic mass of oxygen to get the molar mass of CuO.

Molar mass of CuO = Atomic mass of Cu + Atomic mass of O
Molar mass of CuO = 63.55 g/mol + 16.00 g/mol
Molar mass of CuO = 79.55 g/mol

Therefore, the molar mass of copper(II) oxide (CuO) is 79.55 grams per mole. This value is used in stoichiometry calculations in chemistry to convert between the mass of a substance and the number of moles of that substance.
