<u>Answer:</u> The number of phosphorus atoms in given amount of copper(II) phosphate is 
<u>Explanation:</u>
We are given:
Moles of copper(II) phosphate
= 7.00 mol
1 mole of copper(II) phosphate contains 3 moles of copper, 2 moles of phosphorus and 8 moles of oxygen atoms
Moles of phosphorus in copper(II) phosphate = 
According to the mole concept:
1 mole of a compound contains
number of particles
So, 7.00 moles of copper(II) phosphate will contain =
number of phosphorus atoms.
Hence, the number of phosphorus atoms in given amount of copper(II) phosphate is
