Question

Potassium reacts with aluminum bromide to produce aluminum and potassium bromide. You will generate ____ moles of aluminum when you react 0.372 moles of potassium.

Answer 1

Answer:

You will generate 0.124 moles of aluminum when you react 0.372 moles of potassium

Explanation:

Determine the reaction:

3K + AlBr₃ → Al + 3KBr

Ratio is 3:1

3 moles of K can produce 1 mol of Al

So, 0.372 moles of K, may produce (0.372 .1) /3 = 0.124 moles of Al
