Explanation
This question asks for the relative molecular mass of Copper Oxide (CuO). We can calculate this by adding the relative atomic masses of the Copper (Cu) and Oxygen (O) atoms in the molecule. The relative atomic mass of Copper (Cu) is given as 64 and the relative atomic mass of Oxygen (O) is given as 16. The formula mass or molecular mass is the weighted sum of the atomic masses of the atoms in a molecule. The given molecule, copper oxide (CuO), is made up of one atom of copper (Cu) and one atom of Oxygen (O).Hence, we add these two values to find relative molecular weights:\(M_{1}(CuO) = A_{r}(Cu) + A_{r}(O)\).
