If the concentration of cholesterol is 238mg/100ml:
238 mg ==> 100ml
2380 mg (or 2.38g) ==> 1000ml (1L)
So the concentration will be 2.38 g/L of cholesterol.
if the volume is 5.2 L, the total grams of cholesterol would be :
m = C . V = 2.38g/L * 5.2 L = 12.376 grams of cholesterol.
Answer:
Check explanation section.
Explanation:
Isotopes are chemical species of the same elements with different number of neutrons but the same protons.
Both Chlorine-35 and Chlorine-36 are the same because they are both isotopes of the same elements that is Chlorine. Also, both Chlorine-35 and Chlorine-36 have the same number of protons which has the value equal to 17.
The difference between Chlorine-35 and Chlorine-36 is that Chlorine-35 is stable and has the abundance of 75.77% whole Chlorine-36 is found in trace.
Also Chlorine-35 has a neutrons value of 18 while that of Chlorine-36 is 19.

The process is called fractional distillation. It works by heating up the crude oil inside a chamber to a boil (vaporizing it). Due to the fact that each component of crude oil has a different boiling point, each component of the crude oil will condense at a different height inside the chamber since the chamber gets colder the further up you go away from the heat source. Since each component condenses at different heights in the chamber, there are places to collect condensing liquid at different heights in the chamber (The heights correspond to the boiling point of each component). These collection areas will collect only the component of crude oil that condenses at that temperature. The condensing point is basically the boiling point which means the lower in the chamber that component condenses at, the higher the boiling point for that component is and therefore the heavier that component is (the heavier components get collected near the bottom of the chamber while the lighter components get collected near the top of the chamber).
I hope this helps. Let me know if anything is unclear.
