Scenario: Imagine you are a chemist working for a company that produces ethylene from ethane. Your company wants to increase its production capacity by 20%. You need to determine how much additional ethane you need to procure to achieve this goal.
Task:
Exercise Correction:
**1. Calculate current ethylene production:** * Ethylene production = Ethane processed * Conversion rate * Ethylene production = 1000 metric tons * 0.80 = 800 metric tons **2. Calculate the desired increase in ethylene production:** * Desired increase = Current ethylene production * 20% * Desired increase = 800 metric tons * 0.20 = 160 metric tons **3. Calculate the additional ethane needed:** * Additional ethane needed = Desired increase in ethylene / Conversion rate * Additional ethane needed = 160 metric tons / 0.80 = 200 metric tons **Explanation:** To increase ethylene production by 20%, we need to produce an additional 160 metric tons of ethylene. Since the conversion rate of ethane to ethylene is 80%, we need 200 metric tons of additional ethane to achieve the desired increase. This is because for every 1 metric ton of ethane processed, we get 0.8 metric tons of ethylene.
