d. How many mol SO, are required to make 118 mol CS?

To determine how many moles of SO2 are required to make 118 moles of CS2, we need to use the balanced chemical equation for the reaction.

The balanced chemical equation for the reaction between SO2 and CS2 is:

SO2 + CS2 → CSS + SO

According to the equation, the molar ratio between SO2 and CS2 is 1:1. This means that for every 1 mol of CS2, we need 1 mol of SO2.

Since we have 118 moles of CS2, we will also need 118 moles of SO2.

Therefore, 118 mol SO2 are required to make 118 mol CS2.
