Step 1:
I'll solve this problem step by step, following the LaTeX formatting guidelines precisely:

Step 2:
: Identify the elements in the compound

- The compound is P₂O₅, which contains: - Phosphorus (P) - Oxygen (O)

Step 3:
: Find the atomic masses

- Atomic mass of Phosphorus (P): $$m_{P} = 30.97 \mathrm{g/mol}
- Atomic mass of Oxygen (O): m_{O} = 16.00 \mathrm{g/mol}

Step 4:
: Calculate the number of atoms in the compound

- Phosphorus: 2 atoms - Oxygen: 5 atoms

Step 5:
: Calculate the molar mass

- Total molar mass: $$61.94 \mathrm{g/mol} + 80.00 \mathrm{g/mol} = 141.94 \mathrm{g/mol}
- Oxygen contribution: 5 \times 16.00 \mathrm{g/mol} = 80.00 \mathrm{g/mol}

Final Answer

The molar mass of P₂O₅ is 141.94 \mathrm{g/mol}.
