  • Calculating Carbon Disulfide Percent Yield: A Step-by-Step Guide
    To calculate the percent yield of carbon disulfide, we need to:

    1. Determine the theoretical yield of carbon disulfide.

    2. Compare the actual yield (10.1 g) to the theoretical yield and express the result as a percentage.

    1. Theoretical yield:

    The balanced chemical equation for the reaction between sulfur dioxide and methane to produce carbon disulfide is:

    ```

    CO2 + 2H2S ---> CS2 + 2H2O

    ```

    From the equation, we can see that 1 mole of CO2 reacts with 2 moles of H2S to produce 1 mole of CS2.

    The molar mass of CS2 is 76 g/mol.

    Therefore, the theoretical yield of CS2 can be calculated as:

    ```

    Theoretical yield = 33.4 g SO2 * (1 mol SO2 / 64 g SO2) * (1 mol CS2 / 1 mol SO2) * (76 g CS2 / 1 mol CS2)

    = 40.9 g CS2

    ```

    2. Percent yield:

    The percent yield is calculated by dividing the actual yield by the theoretical yield and multiplying the result by 100.

    ```

    Percent yield = (Actual yield / Theoretical yield) * 100

    = (10.1 g CS2 / 40.9 g CS2) * 100

    = 24.7%

    ```

    Therefore, the percent yield of carbon disulfide is 24.7%.
