The approximate molar mass of lauryl alcohol is 183 g/mol.
As per Raoult's law:
Tb = the freezing point of benzene (5.5oC), Ts = the freezing point of the solution, K = the cryoscopic constant (5.12 K*kg/mol for benzene), and Cm = the molality of the solution.
/M = where ml is the mass of lauryl alcohol and ms is the mass of the solvent.
=K/M
Therefore, M===183 g/mol.
<h3>Lauryl alcohol </h3>
An organic substance called lauryl alcohol is created industrially from coconut or palm kernel oil. It is an alcoholic fat. The use of sodium lauryl sulfate and other sulfate esters of lauryl alcohol as surfactants is extremely common. In shampoos, sodium laureth sulfate, ammonium laureth sulfate, and sodium lauryl sulfate are all utilized. Lauryl alcohol has a floral scent and is flavorless and colorless. In addition to being a flavor-enhancing food additive, lauryl alcohol is also used to create medicines, lubricating lubricants, surfactants, and monolithic polymers. Lauryl alcohol is a kind of emollient used in cosmetics. Lauryl alcohol, a significant scent, and 1-bromododecane, an alkylating agent used to increase the lipophilicity of organic molecules, are both precursors to Lauryl alcohol.
A solution of 5. 00 g of lauryl alcohol in 0. 100 kg of benzene freezes at 4. 1°c. what is the approximate molar mass of lauryl alcohol?

Cars up north require more antifreeze than water as a result of the colder
temperature which makes the coolant in vehicles more prone to freezing.
<h3>What is Freezing point depression?</h3>
This is a situation which occurs when solutes are added to a solvent in
order to reduce the freezing point of the solvent. The impurities help lower
the freezing point of the solvent and is commonly used in vehicles.
This is because cars in the North are exposed to colder temperatures
which could freeze the coolant(solvent).

Answer: the third option, each sub-level electron type has a unique path where it will likely be found.
Explanations:
1) Bhor's model of electrons orbiting the nucleus of the atom was shown to be wrong.
2) The actual model of the atom is the quantum atom model.
3) The quantum atom model depicts the electron in regions called orbitals.
4) The orbitals are the sublevels of energy (or subshells).
These sublevels (orbitals) are identified with the letters s, p, d, and f.
The orbitals s are spherical, the orbitals p are like a dumbbells, d and f orbitals have weirder shapes.
Those orbitasl are kind of electron clouds. The orbitals are defined as regions of the space around the atomic nucleus where the electrons are likely located.
U-238 has 92 protons, 146 neutrons, and 92 electrons.
Rn-222 has 86 protons, 136 neutrons, and 86 electrons.
U-238 is Uranium 238 and Rn-222 is Radon 222.
