Hint: At the point when you hear the word ''moles'' you may think about the creature that tunnels in the ground. In science, the mole is a unit speaking to \[6.022{\text{ }}x{\text{ }}{10^{23}}\] atoms or molecules of a substance. The masses on the periodic table are molar masses.

Complete step by step answer:
The molecular formula for Phosphorus is P.
The SI unit for quantity of material is the mole.
one mole is equal to one moles Phosphorus, or\[30.973761{\text{ }}g\].
STEP 1: To determine the grams first find the normality of molecules
Simply use the formula: \[n\] \[ = \] $\dfrac{m}{M}$
STEP 2: use periodic table to use the mass of a molecule
Always use a periodic table as a kind of perspective when managing moles and mass quantities of the components or compounds.
Phosphorus has a molar mass (M) of \[30.973762{\text{ }}g/mol.\]
Step 3: calculate the final answer
\[m\] \[ = \] \[n\] \[ \times M = 2.3{\text{ }}moles \times 30.973762{\text{ }}g/mol = 71{\text{ }}g\]
Definition molar mass starts with units of grams per mole (g/mol). After calculating the molecular weight of a chemical compound, it tells us how many grams are in\[\;1\] mole of that substance. The formula weight is basically the weight in atomic mass units of all the atoms in a specified formula.

Note:
Every component is requested by expanding the nuclear number, which is reflected in the entire number digit in the upper left or center of each tile. Beneath this nuclear number is the letter symbol or abbreviation for every component. Under this image is the comparing nuclear weight, which is the worth you should change grams over to moles.
