Question

What is the mass of one mole of phosphorous (P) atoms? Express your answer to four significant figures. The mass of 1 mole of phosphorus atoms is ****** grams.

Answer 1

30,9738 grams

Step-by-step explanation:

The atomic mass in the periodic table is expressed in g/mol.

In this case, the atomic mass of phosphorous is 30,9738 grams per mol.

If you do te count:

`1 [mol(P)] * 30,9738 [(g)/(mol) ]=30,9738 [g]`

Answer 2

Answer: The mass of 1 mole of phosphorus atoms is 30.97 g

Step-by-step explanation:

Atomic mass is defined as the mass of an atom of a chemical element that is expressed in atomic mass units. It can also be expressed in grams/mole. It is equal to the mass of atoms that are present in 1 mole of an element.

Phosphorus is the 15th element of the periodic table.

Mass of 1 mole of an atom is equivalent to mass of
`6.022* 10^(23)` number of particles. This number is called as Avogadro's number.

Mass of 1 mole of an phosphorus atom is equal to 30.97 g/mol

Hence, the mass of 1 mole of phosphorus atoms is 30.97 grams.
