Question

paitent has a cholesterol count of 206 mg /dl.
What is the molarity
of the cholesterol in this
patient blood of the molecular mass of cholesterol
is 386.64 gm/M .​

Answer 1

Answer:

Given that,

density = 206 mg/dL , so it will be 2.06 g/L ; since (1mg=10*-3 g ; 1dL=10L )

now molarity (M ) = number of moles of cholesterol / volume of cholesterol solution (in L )

since, density = mass / volume , so volume = mass/ density

M = number of moles of cholesterol * density / molecular mass

M = 1 mole * 2.06 / 386.64 ( 1 mole )

M = 0.00533
