Answer:
24.08 moles of phosphorous are needed to react with 30.1 moles of oxygen.
Step-by-step explanation:
Given data:
Number of moles of O₂ = 30.1 mol
Number of miles of P = ?
Solution:
Chemical equation:
4P + 5O₂ → 2P₂O₅
Now we will compare the moles of phosphorus and oxygen.
O₂ : P
5 : 4
30.1 : 4/5×30.1 = 24.08 mol
So 24.08 moles of phosphorous are needed to react with 30.1 moles of oxygen.
