No, of course not! The only way for it to be true is if the molecular weight of the two compounds (elements) were identical. Looking at a periodic table you see they aren't the same molecular weight and therefore can't have the same number of moles.
A mole is a number of atoms (admittedly a really, really large number). A dozen is also a number. A dozen envelopes doesn't weigh the same as a dozen bricks doesn't weigh the same as a dozen doughnuts. The only way a dozen of anything weighs the same is if the unit (each) weighs the same. The molecular mass is the mass of each unit and unit is the mole!

No
mass / molar mass = moles
the molar mass of Chlorine and of Copper are different
