Question
An illegal street drug known as "Sharp.Z" (Si4H14P2Xe1) from the planet Thalveur has been causing widespread overdoses and deaths across multiple planets. You, as the assistant of the Thalveurian scientist researching Sharp.Z for potential methods of treatment, are required to complete some un gruntwork calculations for your scientist. molar mass mass fraction mol fraction Our of curiosity, you also wonder if it is able to pass through the blood brain barrier of your new alien study-for-hobby subject known as "homo sapeins sapiens a.k.a. humans " of their plant "Earth". will pass through if less than 500 g/molExplanation / Answer
Molar mass of Si4H14P2Xe1-
SI - 28.0855 g/mol x 4= 112.342
H- 1.00794 g/mol x 14 = 14.11116
P- 30.9738 g/mol x 2 = 61.9476
Xe- 131.29 g/mol x 1 = 131.29
112.342 + 14.11116 + 61.9476 + 131.29 = 319.69076g/mol.
Mass fraction
Si- 112.342/319.69076 = 0.35140
H- 14.1111/319.69076 = 0.44139
P- 61.9476/319.69076 = 0.19377
Xe- 131.29/319.69076 = 0.41067
The blood–brain barrier allows the passage of water, some gases, and lipid-soluble molecules by passive diffusion, as well as the selective transport of molecules such as glucose and amino acidsthat are crucial to neural function.I think it won`t pass through the barrier as its size is too large.
The blood–brain barrier (BBB) is a highly selective semipermeable membrane barrier that separates the circulating blood from the brain extracellular fluid in the central nervous system (CNS). The molecular size and its solubility in the lipid are the two factors which determine whether it will pass through the barrier or not.As we dont know whether this molecule which is less than 500 g/mol is lipid soluble or not we cannot determine whether it can pass through the memmbrane or not.
