Phosphorus in mass?
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two main forms, white phosphorus and red phosphorus, but due to its high reactivity, phosphorus has never been found on Earth as a free element.
How do you find the atomic mass of phosphorus?
The atomic mass of phosphorus is 30.97 acres. The molar mass of phosphorus is 123.88 g/mol.
What is the mass of 1 mol of phosphorus?
Explanation: The mass of 1 mole of phosphorus atoms can be expressed in grams per mole (g/mol). This is also called molar mass.If we check the periodic table, the molar mass of phosphorus is About 30.97 g/mol.
