It isn't. The mass of one mole of aluminum is less than the mass of one mole of copper. The number of atoms in one mole of aluminum is the same as the number of atoms in one mole of copper, which is 6.022 x 1023, also known as Avogodro's number.

Why does a mole of copper atoms weigh less than a mole of lead atoms?
Because copper has a smaller molar mass, hence it will have less mass per mole than lead.
Adding copper or magnesium to aluminum creates an alloy that is?
stronger than aluminum
Is copper denser than aluminium?
Stainless steel is heavier then aluminium.
Property of aluminum in hardness?
Aluminum is pretty hard; it is not as hard as steel, but it is harder than copper.
Why aluminum has high thermal expansion coefficient than Copper?
Why aluminium has high thermal expansion coefficient than Copper?"
Does aluminum have lower resistance than copper?
No, aluminum has a higher resistance than copper.
Is copper stronger than aluminum?
no its not copper is a lot more stronger than aluminum
Does a copper heat sink or an aluminum one with a base made of copper work any better than a pure aluminum one?
The thermal conductivity of copper is higher than that of aluminum, and silver is better than either copper or aluminum.
Why does a mole of copper atoms weigh less than a mole of lead atoms?
Because copper has a smaller molar mass, hence it will have less mass per mole than lead.
Compare conductivity of iron copper and aluminum in terms of electricity.?
When compared by volume, copper is best, then aluminum and finally iron. When compared by weight, aluminum is better than copper. You have to compare by volume because aluminum is so much lighter than copper, an aluminum wire that weighed the same as a copper wire would be much bigger and harder to work with.
Adding copper or magnesium to aluminum creates an alloy that is?
stronger than aluminum
Is copper more reactive then aluminium?
No, copper is less reactive than aluminum.
Why aluminium cable cost less than copper cable?
copper cost more to mine then aluminum so aluminum will cost less then copper cable.
Does aluminum or copper produce more electricity?
Copper is more electrically conductive than aluminum (this is because aluminum forms a monomolecular layer of non-conductive aluminum oxide on its surface).
Why are copper wires used in as connecting wires?
The copper wires used connect. Because conductivity of Cooper higher than aluminium but price of Cooper higher than aluminum. If compare between copper and aluminium cable can see at the same current rate diameter of aluminium cable is larger than copper cable.
Which has a larger raduis calcium or copper?
Calcium has a larger radius (not raduis) than copper.
Is barium smaller than aluminum?
Barium (137.327) is larger than aluminum (24.305)
