Answer
Answer:
30.97
Explanation:
Step1: Recall molar - mass concept
The molar mass of an element (in g/mol) is numerically equal to its atomic mass (in u).
Step2: Find atomic mass of phosphorus
The atomic mass of phosphorus (P) from the periodic table is approximately 30.97 u. So, the mass of 1 mole of phosphorus atoms is 30.97 g.
