The number of mole of copper in the sample is 0.008 mole.
Mole is simply defined as the unit of amount in a substance.
The mole of a substance can be obtained by dividing the mass of the subtance by its molar mass i.e
Mole = mass / molar mass
With the above information, we can obtain the mole of copper in the compound as follow:
Mass of copper = 0.5066 g
Molar mass of copper = 63.5 g/mol
<h3>Mole of copper =? </h3>
Mole = mass / molar mass
Mole of copper = 0.5066 / 63.5
<h3>Mole of copper = 0.008 mole </h3>
Therefore, 0.008 mole of copper was initially present in the compound.

Answer:
Say sorry, and then send them a gift.
Explanation:
Answer:
The question is incomplete. The response options are as follows:
I. C-O or C=O
II. C-C
III. C-H
IV. O-H
The answer is: IV>III>I>II
Explanation:
V) O-H is a hydrogen bridge. The hydrogen bridge is characterized by being similar to dipole-dipole bonds.
III) C-H is an ionic bond. The ionic bond occurs when they fuse together due to electron transfer.
I) C=O is a covalent bond. The covalent bond happens when two atoms bond together to create a molecule, sharing its electrons that are in its most superficial layer,
II) C-C is covalent bond.
