Answer:
Explanation:
In this case, we have to start with the <u>chemical reaction</u>:
So, if we start with <u>10 mol of cyclohexanol</u> () we will obtain 10 mol of cyclohexanol (
). So, we can calculate the grams of cyclohexanol if we<u> calculate the molar mass:</u>
With this value we can calculate the grams:
Now, we have as a product 500 mL of . If we use the <u>density value</u> (0.811 g/mL). We can calculate the grams of product:
Finally, with these values we can calculate the <u>yield</u>:
%= (405.5/820)*100 = 49.45 %
See figure 1
I hope it helps!
