Answer 1

To determine the best mole ratio for calculations, it's important to consider the chemical reaction you are dealing with. However, based on the options provided, here are some potential interpretations:

1. **2 mol ZnO : 1 mol C** - Typically suggests a reduction reaction where carbon is used to reduce zinc oxide (ZnO) to zinc (Zn).
2. **1 mol C : 2 mol ZnO** - The inverse of the first option, suggesting the same reaction but framed differently.
3. **2 mol Zn : 1 mol C** - This might suggest a different context, possibly involving the formation of carbon and zinc from another reaction.
4. **2 mol ZnO : 1 mol CO2** - This ratio suggests a different process, possibly involving the combustion or reaction of ZnO producing CO2.

If the context is the reduction of ZnO to Zn using carbon, then the ratio **2 mol ZnO : 1 mol C** would be the most suitable for calculation since it directly reflects the stoichiometry of the reaction where two moles of ZnO react with one mole of carbon.

So, you would likely want to choose **2 mol ZnO : 1 mol C** for your calculations.
