Brodie Hart · Answer 1

0.016 moles of product will obtain.

Explanation:

Given dа ta:

Moles of K = 0.032 mol

Moles of product = ?

Solution:

Chemical equation:

4K + O₂ → 2K₂O

Now we will compare the moles of K with K₂O.

K : K₂O

4 : 2

0.032 : 2/4 * 0.032 = 0.016 mol

0.016 moles of product will obtain.
