Question

For the reaction, calculate how many moles of the product form when 0.032 mol of K completely reacts. Assume that there is more than enough of the other reactant. 4K(s)+O2(g)→2K2O(s) Express your answer using two significant figures.

Answer 1

Answer:

0.016 moles of product will obtain.

Explanation:

Given data:

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.
