How many atoms are in 5 moles of phosphorous (P)?

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.

Explanation:

Lets assume that we have 5 moles of phosphorus. Then you have to multiply the Avogadro number which is 6.03x10^23 by the number of moles which is 5. So,6.03 x 10^23 is the number of phosphorus atoms in ONE mole.

your answer would be “dry”
