Answer :
Final answer:
The number of moles of phosphorus atoms in 186 grams of phosphorus is approximately 6.01 moles, calculated by dividing the mass (186g) by the molar mass of phosphorus (30.97 g/mole).
Explanation:
To calculate the number of moles of phosphorus atoms in 186 grams of phosphorus, you should first know the molar mass of Phosphorus (P). The molar mass of phosphorus is about 30.97 grams/mole. To get the number of moles, we use the formula:
Number of moles = Mass (g) / Molar Mass (g/mole)
Inputting the given data into the equation:
Number of moles = 186 g / 30.97 g/mole ≈ 6.01 moles. So, there are approximately 6.01 moles of phosphorus atoms in 186 grams of phosphorus.
