Follow-up Question
According to the first image, if an unknown copper metal compound, has 37.2% Cu then it is most likely a Copper sulfate. If you compare the %Cu using the 2nd image though, Copper acetate has a closer %Cu value. Why is it Copper sulfate then?

Step 1
The different copper compounds along with their copper composition have been given in the following
step.
Step 2
% Copper in compound
= (mass of Copper in compound / molar mass of compound) x 100 %
Molar mass of Copper = 63.546 g/mol
In all the listed compounds, 1 mol of copper is present. So, mass of copper in all the compounds equals its
Molar mass.
There are many copper compounds out of which 5 have been listed.
