Question

Calculate the mass of constituent elements of Copper Oxide from its molecular

formula CuO.​

Answer 1

Answer:

A Compound Copper Oxide , chemical formula CuO

To Find:-

The mass constituent elements of copper oxide

Solution:-

We know the molecular mass of Copper (Cu) in CuO is 63.54u

and the molecular mass of Oxygen(O) is 16u

So the mass constituent elements of Copper oxide is

=>  63.54u/16u = 3.9712

Learn some more concept -

If you want to know the percentage of elements present in CuO then

       You have to find in the following manner -

The total molecular mass of compound CuO is 63.54+16 = 79.54u

The percentage of Cu present in CuO =  63.54/79.54 *100

                        =>    79.88 % Copper is present in Copper oxide

    3. And the percentage of O present in CuO is =  16/79.54 *100

                        =>    20.11% oxygen is present in Copper oxide
