Answer: 1.204 x 10∧25 atoms are in 5moles of Phosphorous.
Explanation:
We begin by taking note of the fact that, 1 molecule of Phosphorous (P4), is made up of 4 atoms of Phosphorous (P).
Using Avogadro's constant;
1 mole of Phosphorous (P4) contains 6.02 x 10∧23 molecules.
5 moles of Phosphorous would contain; 5 x 6.02 x 10∧23 molecules
= 3.01 x 10∧24 molecules.
As stated earlier, 1 molecule of Phosphorous contains 4 atoms of Phosphorous (P).
3.01 x 10∧24 molecules would contain; 4 x 3.01 x 10∧23 = 1.204 x 10∧25 atoms.
∴ 5 mole of phosphorous contain 1.204 x 10∧25 atoms.
