Final answer:
The weight % of metals in crude oil is typically less than 1%. (Option A).
Step-by-step explanation:
The weight % of metals in crude oil can vary, but typically it is less than 1% (option a). Crude oil is primarily composed of hydrocarbons, which are compounds made up of hydrogen and carbon atoms. While metals can be present in trace amounts, they are generally not a significant component of crude oil.
The weight percentage of metals in crude oil is less than 1%, indicating only a trace amount of metals within its composition.
The question asks about the weight percentage of metals in crude oil. When we are considering the composition of crude oil, metals constitute a very small portion of it. The correct answer is that the weight percentage of metals in crude oil is less than 1%. This means that for every 100 grams of crude oil, there will be less than 1 gram of metals. Crude oil is primarily composed of hydrocarbons, and metals are only present in trace amounts. (Option A).
