The of a phospholipid molecule will seek water, whereas the of the molecules will avoid water.

Head and tail respectively

Explanation:

Phospholipids are made up of the glycerol molecule,the head and the tail.The head contains the phosphate group and it’s hydrophilic which means easy interaction with water and the tail contains fatty acids which repels water.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
