Which of the following is true? which of the following is true? urine osmolality in adults cannot be compared to urine osmolality in children. urine osmolality varies equally among adults as in children. urine osmolality varies more among adults than children. urine osmolality varies more among children than adults.

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.
