How many moles of potassium oxide (K20) will be formed when 1.52 moles of potassium reacts with oxygen according to the following reaction: 4 K + 02 > 2 KO

Answer 1

4K+O₂→2K₂O

Idk if maybe your prof made a typo, but the product should definitely be 2K2O, and NOT 2KO.

Given: 1.52 mol K

Desired: mol K₂O

Conversion factors from the balanced equation:

1. 4 mol K = 2 mol K₂O

Math:

(1.52 mol K / 1) × (2 mol K₂O / 4 mol K)= 1.52×2÷4=0.76 mol K₂O
