Answer:
Fatty acid
Explanation:
A fatty acid is a carboxylic acid with a long chain of 12 or more carbons.
If the molecule has no other distinguishing features, the compound is hexacosanoic acid, CH₃(CH₂)₂₄COOH.
Answer: The given substances are placed in order from most soluble in water to least soluble in water as follows.

Explanation:
It is known that like dissolves like which means a polar compound will be soluble in a polar solvent. And, a non-polar compound will be soluble in non-polar solvent.
Ionic compounds are soluble in polar solvent like water. For example,
is an ionic compound and it is readily soluble in water.
2-butanol (
) is also a polar compound and it will also dissolve in water but to a lesser extent as compared to magnesium chloride.
Whereas both methane and propane are non-polar in nature. But as propane is larger in size as compared to methane so, it will be slightly more soluble in water as compared to methane.
Thus, we can conclude that the given substances are placed in order from most soluble in water to least soluble in water as follows.

THE DISTANCE IN TM SHOULD BE EQUAL TO 162 KM
360 mg / 1000 => 0.36 g
molar mass => 180 /mol
number of moles:
mass of solute / molar mass
0.36 / 180 => 0.002 moles
Volume solution = 200 mL / 1000 => 0.2 L
M = n / V
M = 0.002 / 0.2
M = 0.01 mol/L
hope this helps!
