Question

A 1.83 mol sample of carbon reacts with excess zinc oxide to produce zinc and carbon dioxide. How many moles of zinc oxide are consumed?

Answer 1

3.66 moles of Zinc Oxide are consumed

Step-by-step explanation:

Based on the reaction:

C + 2ZnO → 2Zn + CO₂

Where 1 mole of Carbon reacts with 2 moles of Zin Oxide to produce 2 moles of Zinc and 1 mole of Carbon Dioxide.

To solve this question, we must convert the moles of carbon added to the moles of Zinc Oxide that react using the chemical equation (1mol C = 2mol ZnO):

1.83 moles C * (2mol ZnO / 1mol C) =

3.66 moles of Zinc Oxide are consumed
