Please help me!
To react with 10 moles of O2, how many moles of AlBr3 are needed?​

Answer 1

13.3 mol

Step-by-step explanation:

Given data:

Number f moles of O₂= 10 mol

Moles of AlBr₃ react = ?

Solution:

Chemical equation:

3O₂ + 4AlBr₃ → 2Al₂O₃ + 12Br

Now we will compare the moles of oxygen and AlBr₃

O₂ : AlBr₃

3 : 4

10 : 4/3×10 = 13.3 mol

Thus, to react with 10 moles of oxygen 13.3 moles of AlBr₃ are required.
