By using this formula of vapor pressure:
Pv(solu)= n Pv(water)
when we have Pv(solu)=231.16 torr & Pv(water)= 233.7 torr
from this formula, we can get n (mole fraction of water) by substitution:
231.16 = n * 233.7
∴ n(mole fraction of water) = 0.99
so mole fraction of solution = 1 - 0.99 = 0.01
when no.of moles of water = mass weight / molar weight
= 365g / 18g/mol = 20 moles
Total moles in solution = moles of water / mole fraction of water
= 20 / 0.99 =20.2
no. of moles of the solution= total moles in solution- moles of water
= 20.2 - 20 = 0.2 moles
when we assumed the mass weight of the solution = 16 g (missing in your question should be given)
∴ molar mass = mass weight of solute / no. of moles of solute
= 16 g / 0.2 mol = 80 g/mol
The answer is 'lipids'
hopefully this helps
Moisturizing conditioners is used for hair that has been damaged by strong alkaline shampoos, chemicals or heat styling.
To enhance the feel, texture, look, and manageability of hair, hair conditioner is a cosmetic product for hair care. Its major objective is to lessen friction between hair strands so that brushing or combing may be done more easily and without risking scalp harm.
Electrostatic interactions allow the conditioner's components, particularly positively charged quaternary ammonium species like behentrimonium chloride or polymers referred to as Polyquaternium-XX, where XX is a random number, to adhere to the hair. Once linked, these substances have a variety of outcomes. Their extensive hydrocarbon backbone contributes to lubricating each hair follicle's surface, which lessens friction and makes combing easier.
