<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 
Answer:
2069.85°C
Explanation:
0 K − 273.15 = -273.1 °C
Then,
234 K − 273.15 = 2069.85 °C
Best regards
Atoms of the same chemical element do not always have the same mass because, although the number of protons in the nucleus is the same for all atoms of the same element, the number of neutrons is not. Most elements as they occur naturally on earth are mixtures of several isotopes
hope this will help
